Pre-Darwinian Theories. T he acceptance of biological evolution is an essential part of the modern scientific explanation of the natural world. Most scientists and major religions in the Western World have long since incorporated it into their understanding of nature and humanity. However, some churches still maintain that there was a special and independent creation of every species and that life forms do not change through time from generation to generation. These “creationists” often share beliefs about the Judeo-Christian Bible that were widely held, even by scientists, during the early 19th century and before. By counting the generations of the Bible and adding them to modern history, he fixed the date of creation at October 23, B. During Ussher’s lifetime, debate focused only on the details of his calculations rather than on the approach. Charles Lightfoot of Cambridge University in England had the last word.
Changing environmental conditions cause changes in the distributions of phenotypic traits in natural populations. However, determining the mechanisms responsible for these changes—and, in particular, the relative contributions of phenotypic plasticity versus evolutionary responses—is difficult. To our knowledge, no study has yet reported evidence that evolutionary change underlies the most widely reported phenotypic response to climate change: the advancement of breeding times.
In a wild population of red deer, average parturition date has advanced by nearly 2 weeks in 4 decades.
Aging has long been a topic of consideration in evolutionary theory, from the areas of contemporary evolutionary studies than has been achieved to date.
An appreciation of the fundamental principles of evolutionary biology provides new insights into major diseases and enables an integrated understanding of human biology and medicine. However, there is a lack of awareness of their importance amongst physicians, medical researchers, and educators, all of whom tend to focus on the mechanistic proximate basis for disease, excluding consideration of evolutionary ultimate reasons.
The key principles of evolutionary medicine are that selection acts on fitness, not health or longevity; that our evolutionary history does not cause disease, but rather impacts on our risk of disease in particular environments; and that we are now living in novel environments compared to those in which we evolved. We consider these evolutionary principles in conjunction with population genetics and describe several pathways by which evolutionary processes can affect disease risk.
These perspectives provide a more cohesive framework for gaining insights into the determinants of health and disease. Coupled with complementary insights offered by advances in genomic, epigenetic, and developmental biology research, evolutionary perspectives offer an important addition to understanding disease. Further, there are a number of aspects of evolutionary medicine that can add considerably to studies in other domains of contemporary evolutionary studies. Charles Darwin saw hereditary disease as proof of inheritance of variation Bynum
Different cognitive processes underlie human mate choices and mate preferences
He suggests that organisms which gain beneficial new features quicker have advantages over others and are more variable. Swedish botanist, Carolus Linnaeus , develops the modern hierarchical classification system. The French naturalist Georges Buffon envisages a constantly changing world in which species change over time but rejects the idea that this change could lead to new species. James Burnett, Lord Monboddo suggests that humans descended from primates and that creatures can transform their characteristics in response to the environment over long time intervals.
Erasmus Darwin proposes that all warm-blooded animals arose and differentiated from a single form, and anticipates the idea of natural selection.
But by applying a bit of game theory – where mathematics is used to understand Monogamy is not an exclusively male evolutionary strategy. The world of dating introduces an even more complicated picture, partly.
The theory of evolution by natural selection, first formulated in Darwin’s book “On the Origin of Species” in , is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
More simply put, the theory can be described as “descent with modification,” said Briana Pobiner, an anthropologist and educator at the Smithsonian Institution National Museum of Natural History in Washington, D. The theory is sometimes described as ” survival of the fittest ,” but that can be misleading, Pobiner said. Here, “fitness” refers not to an organism’s strength or athletic ability, but rather the ability to survive and reproduce.
For example, a study on human evolution on 1, students, published online in the journal Personality and Individual Differences in October , found that many people may have trouble finding a mate because of rapidly changing social technological advances that are evolving faster than humans. In the first edition of “On the Origin of Species” in , Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale.
As a hypothetical example, Darwin used North American black bears, which were known to catch insects by swimming in the water with their mouths open:.

Her job involves incorporating theory and academic research into customer analysis, building a conceptual framework for insights into online consumer behavior. The counter-intuitive truth is that Tinder actually provides users with all the information they need to make an informed first impression about a potential long-term mate. And it does so by matching our human evolutionary mechanism. Although we always ascribe our decisions to a rational, conscious-brain motivation, this supposed motivation is never the entire reason for our decisions; in fact, it often has nothing to do with it!
We like to think of ourselves as rational human beings that base our decisions on logical processes, but most of our decisions occur unconsciously and based on minimal information. Tinder exposes its users to two types of factors: rational Geographical Distance and Age and emotional Appearance and Requited Interest.

Science never takes places in a void and evolutionary thought is no exception. Although Charles Darwin is considered to be by many the “father” of evolutionary thought, he was in fact aided and guided by the works of many scientists before him.
Good news: US classrooms are warming to evolution, thanks in part to scientist outreach
When it comes to the heated subject of differences between how men and women behave, debate in psychology has centered on mate preferences and general interests. The available research shows that when it comes to heterosexual mating preferences, men are relatively more interested in physical beauty, while women are relatively more interested in earning capacity.
As for general interests, men are more interested in physical things, while women are more interested in people. Even the staunchest evolutionary psychologists would acknowledge these are partially overlapping bell curves: There are plenty of men who are fascinated by other people, and plenty of women looking for physical beauty in a partner above all else.

Tinder and evolutionary psychology: The science behind what men and women swipe for, and why
Over the last 25 years, a large amount of research has been dedicated to identifying men’s preferences for women’s physical features, and the evolutionary benefits associated with such preferences. Today, this area of research generates substantial controversy and criticism. I argue that part of the crisis is due to inaccuracies in the evolutionary hypotheses used in the field. For this review, I focus on the extensive literature regarding men’s adaptive preferences for women’s waist-to-hip ratio WHR , which has become a classic example of the just-so storytelling contributing to the general mistrust toward evolutionary explanations of human behavior.
The issues in this literature originate in the vagueness and incompleteness of the theorizing of the evolutionary mechanisms leading to mate preferences.
Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the.
He devoted his youth to his work and in his 30s decided to marry his cousin. Instead, the piece is about sex differences and a batch of newer studies suggesting men and women are more alike than scientists had assumed — especially when it comes to promiscuity and pickiness. This should have been a great story. But the author, Dan Slater, tries to turn these sex difference studies into an attempted debunking of evolutionary psychology. The piece not only fails to make a compelling case but gives only a superficial treatment of the science presented.
Slater names three influential figures in shaping and popularizing an evolutionary view of human behavior — Robert Trivers, David Buss and Steven Pinker. The piece also tries to make the case that a more symmetrical view of male and female sexual desires would somehow disprove the role of evolution in human behavior. But why? In many animals, the males and females are quite parallel in choosiness and promiscuity.
Are those animals shaped any less by evolution?
Tinder And Evolutionary Psychology
Charles Darwin is more famous than his contemporary Alfred Russel Wallace who also developed the theory of evolution by natural selection. Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the s B. Noting that human babies are born helpless, Anaximander speculated that humans must have descended from some other type of creature whose young could survive without any help.
He concluded that those ancestors must be fish, since fish hatch from eggs and immediately begin living with no help from their parents. From this reasoning, he proposed that all life began in the sea. Anaximander was correct; humans can indeed trace our ancestry back to fish.

The latter has been split into two separate entries. Prior to the second half of the nineteenth century, the term was used primarily, if not exclusively, in an embryological sense to designate the development of the individual embryo. In the s the term was used in some contexts to designate species change Bowler Darwin himself did not use this specific term for his theory until the Descent of Man The issues will be examined under the following headings:.
In many respects, the general idea of the possibility of species change is an old concept. The reflections of Empedocles ca. These Presocratic speculations combined naturalistic myths of origins with reflections on the workings of chance-like processes to create a naturalistic account of the origins of existing forms of life see the entry ancient atomism. Particularly as the Presocratic Atomist speculations were restated by the Roman poet Titus Lucretius ca. The speculative accounts of the early atomists were, however, opposed on several levels by the subsequent mainstream Platonic, Neo-Platonic, Aristotelian, and Stoic philosophical traditions.
The writings of Plato — BCE , particularly his long creation myth, Timaeus — the only Platonic dialogue available continuously in the Latin Western tradition—provided an influential non-Biblical source for arguments against the Atomist tradition. This dialogue serves as the locus classicus for the notion of an externally-imposed origin of living beings through the action of an intelligent Craftsman demiurgos who orders a mathematically-conceived matter into a rational cosmos that includes living beings in accord with eternal archetypes or forms, realizing through this activity both aesthetic and rational ends.
Particularly as developed in the influential writings of the Greek physician Claudius Galenus — CE , a long heritage in the life sciences relied upon anatomy as evidence of rational design.
Was Darwin Wrong about Dating or Was the New York Times Wrong About Evolutionary Psychology?
Evolution is change in the heritable characteristics of biological populations over successive generations. Different characteristics tend to exist within any given population as a result of mutation , genetic recombination and other sources of genetic variation. The scientific theory of evolution by natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the midth century and was set out in detail in Darwin’s book On the Origin of Species.
This is followed by three observable facts about living organisms: 1 traits vary among individuals with respect to their morphology, physiology and behaviour phenotypic variation , 2 different traits confer different rates of survival and reproduction differential fitness and 3 traits can be passed from generation to generation heritability of fitness.

By Saul McLeod , updated John Bowlby – was a psychoanalyst like Freud and believed that mental health and behavioral problems could be attributed to early childhood. Lorenz showed that attachment was innate in young ducklings and therefore has a survival value. During the evolution of the human species, it would have been the babies who stayed close to their mothers that would have survived to have children of their own.
Bowlby hypothesized that both infants and mothers have evolved a biological need to stay in contact with each other. Bowlby believed that attachment behaviors such as proximity seeking are instinctive and will be activated by any conditions that seem to threaten the achievement of proximity, such as separation, insecurity, and fear.

Bowlby’s Evolutionary Theory of Attachment. Bowlby (, ) was very much influenced by ethological theory in general.
Scientists have proved one of Charles Darwin’s theories of evolution for the first time — nearly years after his death. Laura van Holstein, a PhD student in Biological Anthropology at St John’s College, University of Cambridge, and lead author of the research published today March 18 in Proceedings of the Royal Society , discovered mammal subspecies play a more important role in evolution than previously thought.
Her research could now be used to predict which species conservationists should focus on protecting to stop them becoming endangered or extinct. A species is a group of animals that can interbreed freely amongst themselves. Some species contain subspecies — populations within a species that differ from each other by having different physical traits and their own breeding ranges. Northern giraffes have three subspecies that usually live in different locations to each other and red foxes have the most subspecies — 45 known varieties — spread all over the world.
Humans have no subspecies. In Chapter 3 of On the Origin of Species Darwin said animal lineages with more species should also contain more ‘varieties’. Subspecies is the modern definition. My research investigating the relationship between species and the variety of subspecies proves that sub-species play a critical role in long-term evolutionary dynamics and in future evolution of species.
And they always have, which is what Darwin suspected when he was defining what a species actually was. On the Origin of Species by Means of Natural Selection, was first published in after Darwin returned home from a five-year voyage of discovery. In the seminal book, Darwin argued that organisms gradually evolved through a process called ‘natural selection’ — often known as survival of the fittest.
His pioneering work was considered highly controversial because it contradicted the Bible’s account of creation.
