Do Epigenetic Changes Influence Evolution?
Katarina Zimmer | Nov 1, 2022 | 10+ min read
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

Evolutionary Applications
Stephen Wolpe | Sep 1, 1997 | 2 min read
Avraham Sonenthal (Letters, The Scientist, July 7, 1997, page 10) challenges readers to come up with "a practical application of biology that would have been impossible were it not for the hypothesis of evolution." While one can never prove that something would have been impossible, there are a number of very practical applications that would be highly unlikely were it not for evolutionary theory. The most obvious application is the use of animal testing for biological and pharmaceutical resea
