The Baldwin effect only posits that learning ability, which is genetically based, is another variable in / contributor to environmental adaptation. First proposed during the Eclipse of Darwinism in the late 19th century, this effect has been independently proposed several times, and today it is generally recognized as part of the modern synthesis .
Skeletal mount (note damaged skull) Presently, most authorities consider the southern cassowary monotypic, but several subspecies have been described. [3] It has proven very difficult to confirm the validity of these due to individual variations, age-related variations, the relatively few available specimens (and the bright skin of the head and neck – the basis upon which several subspecies ...
This behavioral adaptation coincides with the chimpanzee's ability to distinguish kin from non-kin (referred to as visual kin selection) allowing chimps to formulate large, complex societies, where they use altruistic methods to ensure their genes persist in future generations. [7]
When applying synurbization to circumstances of urbanization where species have adapted, that adaptation does not occur by accident. [1] Animals making adaptations to the environment change are often only doing so because of urban expansion into their current environments—e.g., the expansion of cities removing forested areas occupied species ...
