Fossils from Greece and Bulgaria of an ape-like creature that lived 7.2 million years ago may fundamentally alter the understanding of human origins
Researchers have unearthed stone tools and mastodon bones in California which show that humans had reached the Americas far earlier than previously known.
The oldest-known forerunner of dinosaurs, dating back to the Triassic Period, is shaking up the expectations of palaeontologists about dinosaur evolution.
Until now, the oldest-known plants were 1.2-billion-year-old red algae fossils from the Canadian Arctic.
Researchers say many tree species populating the Amazon region appear to be abundant because they were cultivated by people who populated the area before Europeans arrived more than five centuries ago.
It was primordial microbes, like those described in a recent study, that set in motion the evolutionary march toward complex life and, eventually, the appearance of humans 200,000 years ago.
Scientists have found that the world’s largest land mammal sleeps two hours per day on average and some days not at all, and does so mostly standing up.
A technique using high-powered lasers to reveal hidden soft tissue alongside bones in fossils is giving scientists insight into one of the major evolutionary transitions in the history of life: small feathered dinosaurs taking flight as birds.
The surprising fossil discovery showed creatures flourishing in the aftermath of a mass extinction that erased 90% of species.
Dinocephalosaurus is the first member of archosauromorphs, which includes birds and crocodilians, known to give birth to live young.
Scientists say a tiny marine creature from China that lived about 540 million years ago may be the earliest known animal in the lengthy evolutionary path that led to humans.
Scientists suspect the tail belonged to a type of two-legged, bird-like dinosaur called a maniraptoran, which would have been no more than 15 cm long.
Average life expectancy continues to increase and more people are reaching extreme old age. But, researchers say, people who reach 110 today have no greater life expectancy than those who lived to 110 in the 1970s.
An analysis of gas bubbles trapped in ancient basalt rock that formed from ancient lava flows showed the planet back then possessed a much thinner atmosphere, with air pressure half of what it is today.
CT scans of the skull revealed its (Sarmientosaurus’) brain structure and provided close understanding of its hearing, sight and feeding behavior.
