The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication ...

Evolution is a complicated thing. Much of modern evolutionary biology seeks to reconcile the seeming randomness of the forces behind the process — how mutations occur, for example — with the ...

In a first-of-its-kind experiment tracing evolution across 25 generations, scientists have discovered that marine copepods—the tiny crustaceans at the heart of the ocean food web—rely on a largely ...
