What is the Adaptationist approach?
Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism’s ancestors. The trait is a variation of an earlier form.
What are the main critiques of the Adaptationist Programme?
We fault the adaptationist programme for its failure to distinguish current utility from reasons for origin (male tyrannosaurs may have used their diminutive front legs to titillate female partners, but this will not explain why they got so small); for its unwillingness to consider alternatives to adaptive stories; for …
Are just so stories myths?
The “Just So” Story (also known as a “pourquoinote story,” “origin story,” or “aetiological tale”note from the Ancient Greek αἴτιον, “cause”) is a myth or folktale which, to quote Wikipedia , “purports to describe the origin of some feature of the natural or social world.” The question, often posed to an adult by a …
What is substrate neutrality?
English term or phrase: substrate neutrality. A defining property of an algorithmic process is its “substrate neutrality”: An algorithm does a job and returns a result whatever the input. Dennett concludes that natural selection, as an algorithm, is also substrate neutral.
How does evolutionary psychology explain human behavior?
Evolutionary psychology uses evolutionary theory to explain similarities in psychological characteristics. According to evolutionary psychologists, patterns of behavior have evolved through natural selection, in the same way that physical characteristics have evolved.
What is the Adaptationist Programme according to Gould and Lewontin?
According to Gould and Lewontin, the adaptationist program, each part of an organism had a particular shape due to the action of natural selection.
What are spandrels in evolution?
An evolutionary spandrel is a physical structure or behavioural characteristic that is a by-product from some other functional adaptation. But despite some apparent examples, truly useless spandrels are hard to find within evolutionary biology.
How the elephant got its trunk Kipling?
He wanted to know what the crocodile had for dinner. Since no one would tell him, he went down to the banks of the Limpopo to find out for himself. When he bent down to see, the crocodile bit his nose – and pulled until it was ‘nearly five feet long’. That, Kipling smiled, was how the elephant got its trunk.
What is a just so explanation?
In science and philosophy, a just-so story is an untestable narrative explanation for a cultural practice, a biological trait, or behavior of humans or other animals. Such tales are common in folklore and mythology (where they are known as etiological myths—see etiology).
What is an evolutionary explanation?
Evolutionary explanations theorize or explore empirically how natural selection shaped human social behavior, social organization, social change, and cultural evolution by causing humans to behave in ways that maximize their inclusive fitness in past and current environments.
How do behaviorists explain behavior?
Behaviorism focuses on the idea that all behaviors are learned through interaction with the environment. This learning theory states that behaviors are learned from the environment, and says that innate or inherited factors have very little influence on behavior.
