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 ...

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

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists ...

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 ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

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 ...

The evolutionary blueprint for hands was borrowed in part from a much older genetic plan for our nether regions, a new study suggests. Researchers armed with CRISPR looked to the embryos of zebrafish ...

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 ...

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 ...

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 ...

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 ...
