Evolution

How did we get limbs from ancestral fish fins? It's a fascinating topic, a science enigma. Our first four-legged land ancestor came out of the sea about 350 million years ago. Watching a lungfish,…

Species living together are not forced to evolve differently to avoid competing with each other, a notion that that has been debated since the early days of natural selection. By focusing on…

 A new hand bone from a human ancestor who roamed the earth in East Africa approximately 1.42 million years ago has been found at the 'Kaitio' site in West Turkana, Kenya.  Humans…

The home team holds the advantage over visitors, at least in the plant world, but a handful of genetic adaptations could even the playing field, according to a new paper. Genetic tradeoffs, in part,…

The genome sequence of a 24,000-year-old Siberian individual demonstrates genomic signatures that are basal to present-day western Eurasians and close to modern Native Americans and…

Everyone has a hypothesis about the 'birthplace of life' and a new paper adds clay to that list. In simulated ancient seawater, clay forms a hydrogel, a mass of microscopic spaces capable of soaking…

A new paper in Cell Reports finds that it doesn't take a lot of genetic changes to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Once…

A new collection featuring research on the complex evolutionary cascade theory that made the unique gigantism of sauropod dinosaurs possible has now been published in PLOS ONE. Sauropod dinosaurs…

Though the largest Sperm whales weigh up to 50 tons and and the smallest bat barely reaches a gram, they share something in common. They both use echolocation, biological sonar, for hunting.…

Pigs, jellyfish and zebrafish don't seem to have much in common with each other, much less humans, but the different species are all pieces of a puzzle which is helping to solve the riddles of…
