Three nearly identical genes could help explain how 0.5 liters of gray matter in early human ancestors became the 1.4-liter organ that has made our species so successful and distinctive.
Discovering something for the second time might sound like a letdown. Not for ecologists in Hawaii, who have found that spider-eating spiders on four islands there independently evolved the same colors: gold, black, and white. This rare example of parallel evolution, which has also been seen in one other Hawaiian spider, could help clarify one of biology’s biggest mysteries: how and when evolution repeats itself.
The mating display of the male bird of paradise owes its optical extravagance to a background so black it is the envy of telescope and solar panel engineers, according to a new study published Jan. 9 in the journal Nature Communications.
Humans could be the reason why there will be a huge burst of evolution happening to creatures around the world.
Speculating about what aliens look like has kept children, film producers and scientists amused for decades. If they exist, will extra terrestrials turn out to look similar to us, or might they take a form beyond our wildest imaginings? The answer to this question really depends on how we think evolution works at the deepest level.
We may have to revise our concept of reality, because numerous prominent scientists consider that there is a chance for our world to be a refined hologram, and everything we perceive to be in fact blips of data on a cosmic screen.
Early life forms on Earth are likely to have mutated and evolved at much higher rates than they do today, suggests a new analysis from researchers at the University of North Carolina.
I think the fossil evidence shows that modern malaria vectored by mosquitoes is at least 20 million years old,
