Darwin’s bridge was that species would not diverge into different species if they had strong enough interactions among individual or similar species. As long as these interactions existed, they would be able to reproduce. In his theory, Da ...

Philosophically speaking, how many species concepts are there?
... It’s an old question in biology: what is a species? Many different answers have been given over the years, and there are indefinitely many “definitions” in the literature. Adding to R. L. Mayden’s list of 22 definitions (Mayden, 1997) , I counted 26 in play since the Modern Synthesis (2009a), and a ...
