Scientists successfully grew Asgard archaea in the lab and took detailed images.
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 fossil skull from a toothy early relative of today's birds shows a weirdly modern skull configuration, raising new questions about the early evolution of birds.
Ancient mammals were better adapted than nonavian dinosaurs to survive the Chicxulub asteroid impact.
Organisms that reproduce quickly can quickly evolve into new species, while geographic barriers can lead to new species formation over tens of millions of years.
Around the time the dinosaurs died out, penguins became swimmers. New research reveals their aquatic evolution.
Scientists figured out the origin of warm-bloodedness in mammals by analyzing the ears of 341 living and extinct species.
A perplexing mystery fish may have finally been placed on the evolutionary tree of life as an ancestor of all four-limbed animals, also known as tetrapods.
Squid, octopus, and other cephalopods are genetic rulebreakers who have scrambled their genomes, perhaps allowing them to evolve their impressive smarts.
A pair of Charles Darwin's notebooks, which were stolen in late 2000, have been anonymously returned to the library that once held them.
Scientists reexamined the fossil of a strange Cambrian sea creature and found that it is related to the 'weird wonder' Opabinia.
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.
