Evolution describes changes in inherited traits of populations through successive generations. To fully understand the science of ecology, one must first be able to grasp evolutionary concepts. Aa Aa ...

Every community comes to a crossroads: should they transform via evolution versus revolution? Make no mistake, transforming a local community is a complex undertaking that can be approached through ...

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

It is often assumed that modern humans are no longer evolving. But there is now considerable agreement among scientists that evolution is still affecting our species—and this process is taking place ...

The version of evolution proposed by Charles Darwin focused on slow, incremental changes that only gradually build into the sort of differences that separate species. But that doesn’t rule out the ...

Even a single gene, reshuffled or regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a recent study of wheatear birds. A study was recently published in the ...

HOUSTON – (Oct. 9, 2023) – With species the world over on the move due to climate change, a unique experiment in the wake of 2017’s Hurricane Harvey has revealed a way that species can instantly ...

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...

How do scientists diagram evolutionary relationships? Scientists represent evolutionary relationships with tree diagrams (also called cladograms) because new life forms appear the way new branches ...

In 2017, unprecedented rainfall from Hurricane Harvey caused local extinctions of populations of soapberry bugs. This allowed researchers from Rice University and UC Davis to observe evolution at work ...
