Female sea urchins hedge their bets in the mating game
Sleeping around pays off for females, according to an international team of evolutionary biologists.
Program models more detailed evolutionary networks from genetic data
The tree has been an effective model of evolution for 150 years, but a Rice University computer scientist believes it's far too simple to illustrate the breadth of current knowledge.
New thinking about species extinctions reinforces need for big populations
Many species are on the cusp of disappearing forever, from the Yosemite toad to the cave katydid in South Africa. One of the pivotal tipping points is when a population becomes very small and is geographically ...
Fine-tuning of bitter taste receptors may be key to animal survival
One key to animal survival is bitter taste——the better to avoid ingesting potentially harmful poisons or foods. The evolution of bitter taste has been a hot topic amongst evolutionary biologists, and with more and more ...
How dinosaur arms turned into bird wings
Although we now appreciate that birds evolved from a branch of the dinosaur family tree, a crucial adaptation for flight has continued to puzzle evolutionary biologists. During the millions of years that elapsed, wrists went ...
Man-made evolution is happening, and it's time to control it
Planting pesticide-free cotton as a refuge for the pert pink bollworm caterpillar has slowed bollworms in neighboring cotton fields from developing resistance to pesticides because they breed with the pesticide-free ...
Galapagos hawks hand down lice like family heirlooms
Say what you will about the parasitic lifestyle, but in the evolution of life on Earth, it's a winner.
When genes play games: Algorithm helps explain sex in evolution
What do you get when you mix theorists in computer science with evolutionary biologists? You get an algorithm to explain sex.
Why the urge to find 'Nemo' has helped fish diversify
Caring parents foster successful offspring, or so the thinking goes. But for reef fishes, such as Disney's charismatic clownfish, Nemo, the effects of parental care stretch right across evolutionary time ...
Could biology explain the evolution of religion?
For a biologist like me, the interesting questions about religion have always been where did it come from and why did it evolve? I taught evolutionary biology in a Catholic University in the most Catholic country in the world – Brazil. Some of my colleagues here in the UK thought that must have bee ...
Shorter lives for male fruit flies forced to compete
A University of Liverpool study of fruit flies has revealed that males forced to compete with other males become less attractive to females and die young.
Beneficial organisms react differently to parasite drug
The substance ivermectin has been used for more than thirty years all over the world to combat parasites like roundworms, lice and mites in humans, livestock and pets. The active ingredient belongs to the chemical group of ...
Strictly yeast: Ribosomal dance leaves evolutionary footprints
Researchers at the National Collection of Yeast Cultures at the Institute of Food Research have turned a problem in evolutionary biology into a new tool to better understand phylogeny in closely related species. ...
It's Darwin Day, a celebration of science and reason
Happy Darwin Day! Is that even an appropriate thing to wish somebody? Especially so close to Valentine's day?
