May 20, 2021
Author(s)
Alejandro Cano, Hana Rozhonova, Arlin Stoltzfus, David McCandlish, Joshua Payne
Evolutionary adaptation can be conceived as a series of substitutions representing mutation-fixation events. The changes that are more likely will appear more frequently in the aggregate spectrum of adaptive substitutions. Recent studies establish that
