Squid, octopus, and other cephalopods are genetic rulebreakers who have scrambled their genomes, perhaps allowing them to evolve their impressive smarts.
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.
A pair of Charles Darwin's notebooks, which were stolen in late 2000, have been anonymously returned to the library that once held them.
Researchers compared the skulls of domesticated house cats to the skulls of their closest wild ancestor, and found that cat brains are definitely shrinking.
Reference In 1859, Charles Darwin published his ideas that humans and animals change over time. But what is the Theory of Evolution?
Natural selection has been acting on more than 700 human genes over the last 3,000 years, perhaps contributing to the persistence of disorders like inflammatory bowel disease.
Fossils from northwestern Canada may represent ancient sponges dating to 890 million years ago, making them the oldest known examples of animal life.
Analysis of a well-preserved fossil from South Africa provided a "missing puzzle piece" for the evolution of dinosaur respiration.
A new study on human cultural evolution argues that humans evolve much faster as cultures than as individual organisms, molding our genes in the process.
The ancestors of vampire squid started trawling deep, oxygen-poor waters around 30 million years ago, a long-lost fossil rediscovery reveals.
Earth could have hosted islands as long as 4 billion years ago, leaving open the possibility that the first life could have evolved on land rather than near hydrothermal vents.
Thick facial hair could cushion the face and jaw, lending protection against punches, kicks and other combat blows.
Gigantopithecus, an enormous extinct ape that lived in Asia millions of years ago, was a close relative of the modern orangutan.
A look at 4.5 billion years of Earth's history tells us that intelligence, including extraterrestrial intelligence, is unlikely to evolve.
Humans did not evolve from apes, gorillas or chimps. We share a common ancestor and have followed different evolutionary paths.
