Forced to respond to a climate that’s changing faster than it ever has, it remains unclear whether species’ adaptations can keep pace.
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
Short Shrift to Evolution?
Barry Palevitz and Ricki Lewis | Feb 1, 1999 | 7 min read
Editor's Note: In this essay, the authors--both scientists and writers--discuss recent news stories on evolution and express their opinions on how the stories were handled by the mainstream press. Evolution took center stage at the National Association of Biology Teachers (NABT) annual meeting in Reno, Nev., Nov. 3-8, 1998. If the teachers needed a theme, evolution was a logical choice--after all, it underlies and unifies contemporary biology. But NABT had other fish to fry. Despite a spate of c
Hybrid Animals Are Not Nature’s Misfits

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.

Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
