Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below.
1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25] [26] [27] 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats. [28] 3.
The argument was first proposed by Alvin Plantinga in 1993 and "raises issues of interest to epistemologists, philosophers of mind, evolutionary biologists, and philosophers of religion". [1] The EAAN argues that the combined belief in both evolutionary theory and naturalism is epistemically self-defeating. The argument for this is that if both ...
Many have noted the lack of research on the subject. While acknowledging the "phenomenon of genetic sexual attraction", Eric Anderson, a sociologist and sexologist, noted in a 2012 book that "[t]here is only one academic research article" on the subject, and he critiqued the paper for using "Freudian psycho-babble".
