Zach B. Hancock | Is Evolution a Theory in Crisis? @talkpopgen | Uploaded January 2024 | Updated October 2024, 6 hours ago.
The popular press has been buzzing for years with claims that evolutionary theory is undergoing a rapid transformation - discoveries in molecular, cellular, and developmental biology are radically changing our view of nature. But do these claims have any factual basis or is it all just hype?
In this video, I evaluate calls for an "extended evolutionary synthesis" by clarifying the history of the Modern Synthesis, argue that it's distinct from contemporary evolutionary theory, and ultimately conclude that there have been no new mechanisms of evolution discovered by any emerging field in biology since the 1920s. Thus, evolutionary theory is neither a "theory in crisis" nor in need of major extension or reformulation.
