A group of humans migrating out of Africa some 40,000 to 70,000 years ago mingled with an as-yet unknown branch of humanity, three new studies have found.
Evolution is among the most substantiated concepts in science and is the unifying theory of biological science. Charles Darwin co-originated, with Alfred Russel Wallace, the theory of evolution by natural selection. His masterwork, the 1859 "Origin of Species," offered ample evidence for evolution having occurred, as well as the first strong explanation for its mechanism, natural selection. Modern evolutionary theory incorporates these concepts: species change over time; genetic mutations are responsible for the changes; individuals with beneficial genetic mutations will survive preferentially compared with their competitors, in a process known as natural selection; those successful individuals' more numerous offspring will spread the beneficial genetic constructs throughout the population; when enough genetic changes reproductively isolate a population, that population has become a new species. Here you'll find news and information on evolution and the battle with proponents of so-called creation science.
Ancient human migrations out of Africa may have been driven by wobbles in Earth's orbit and tilt that led to dramatic swings in climate, a new study finds.
Biologist and writer Carin Bondar leads the way into the intriguing world of animal sexual practices in her new book, "Wild Sex."
When it comes to giraffes, can you spot the difference? A new study reveals there's more to the animals' species diversity than once suspected.
Some 360 million years ago, a school of juvenile lizard-like creatures ─ with no parental chaperones around ─ perished in a watery grave in what is now Greenland.
Small and furry gliding mammals called colugos are primates' close relatives, scientists have discovered
Our relationship with the bacteria in our guts extends far back into our evolutionary past — before modern humans even existed, a new study finds.
A taste for alcohol may be more widespread in the primate lineage than suspected, and is linked to genetic factors, a new study suggests.
Scientists found that modern-human footprints and the tracks left behind by Homo erectus are nearly indistinguishable.
A robot modeled after the mudskipper fish is helping scientists understand how animals moved millions of years ago, when they first transitioned to walking on land.
The most recently discovered extinct human species may have lived less than 1 million years ago, suggesting the small-brained hominin lived alongside several other hominins.
In the dark ocean depths, there are fish that generate their own eerie glow — and a new study finds that far more of them do this than scientists suspected.
The newfound ancestors may have been even littler than the hobbits, and date much further back in time, from some 700,000 years ago.
A dead whale that washed up on a southern Australia beach has something peculiar in its mouth: a sharp and pointy fang, say the researchers who examined it.
