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.
Hybrid Animals Are Not Nature’s Misfits
Ashley Yeager | May 1, 2021 | 8 min read
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.

Animal Divorce: When and Why Pairs Break Up
Catherine Offord | Jun 1, 2022 | 10+ min read
Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.

Evolution: It's Not Just A Single Theory, It's A Lot Of Theories
Mick Wycoff | Mar 29, 1992 | 5 min read
The Darwinian would say, "Gene dissemination: Successful competition in the hunt allows the fox to survive and breed, maximizing its individual representation of genes in the population. That's how natural selection works." The ecological biologist would say, "Sure, but first and foremost, the fox is eating the quail to stay alive. It's a cross-species energy transaction between two individual members of a tightly integrated ecosystem. As a result, the fox survives and manages to pass genes o

Epigenetics May Remember Ancestors’ Mutations
Holly Barker, PhD | Dec 1, 2022 | 4 min read
Parents’ mutations, even if they’re not inherited by offspring, could affect subsequent generations through changes to epigenetic marks, a study finds.
