Oct. 20, 2016 — Eukaryotic cells, including human cells, form paired condensed chromosomes before cell division. The paired chromosomes are then equally divided into the daughter cells. Prokaryotic cells, including ... read more

Oct. 13, 2016 — The first animals evolved from their single-celled ancestors around 800 million years ago, but new evidence suggests that this leap to multi-celled organisms in the tree of life may not have been ... read more

Oct. 13, 2016 — The evolutionary history of thousands of protein modifications in 18 related species have now been reconstructed by a team of scientists. Their findings highlight a previously unknown strategy for ... read more

Oct. 12, 2016 — The oldest known vocal organ of a bird has been found in an Antarctic fossil of a relative of ducks and geese that lived more than 66 million years ago during the age of ... read more

From Unknown to Beardog: Findings Rescue Fossils from 'Trashbin' Genus

Oct. 12, 2016 — A new study identifies two fossils previously thought to be generic carnivorans (a large, diverse order of mammals) as some of the earliest known members of the beardog family. These fossils are from ... read more

Oct. 11, 2016 — A genomic analysis of 28 dog breeds has traced the genetic history of the remarkable Fonni's Dog, a herd guardian endemic to the Mediterranean island of Sardinia. The results reveal that the ... read more

Oct. 10, 2016 — About 100 million years ago, a lowly amoeba pulled off a stunning heist, grabbing genes from an unsuspecting bacterium to replace those it had lost. Now scientists have solved the mystery of how the ... read more

Oct. 7, 2016 — Although our knowledge of the human DNA is extensive, it is nowhere near complete. For instance, our knowledge of exactly which changes in our DNA are responsible for a certain disease is often ... read more

Oct. 7, 2016 — A spider looking to immigrate to a different environment is three to four times more likely to survive if it goes by itself, as opposed to as part of a group, new research ... read more

Oct. 7, 2016 — How do key innovations in the animal kingdom arise? To explore this question, evolutionary biologists studied Gonatodes, a genus of dwarf geckos. In the process, the researchers found a ... read more

Oct. 6, 2016 — Tarsiers -- tiny, carnivorous primates -- are our distant cousins, according to scientists who sequenced and analyzed the tarsier genome. Their findings place tarsiers on the evolutionary branch that ... read more

Oct. 5, 2016 — Take a glance around the oceans, rivers and lakes of today and you'll confront an astonishing diversity of fish, from narrow-bodied eels to the 25-foot-long giant oarfish to delicate, fluttering ... read more

Oct. 5, 2016 — New information necessitates revising the scenarios on how the enormous species richness in Amazonia has evolved and which factors define species ... read more

Oct. 5, 2016 — Periods of deep, clear water in Lake Malawi over the past 800,000 years coincide with bursts of species diversification, researchers show in a new ... read more

Novel Mechanism to Steer Cell Identities Gives Clue on How Organisms Develop

Oct. 5, 2016 — Scientists discovered a new way in which microRNAs can determine the fate of cells in the course of their development. This could be a key to understanding how complex organisms are built, say ... read more

Oct. 4, 2016 — The new information necessitates revising the scenarios on how the enormous species richness in Amazonia has evolved, and which factors define species distributions, say ... read more

Oct. 3, 2016 — The earliest ancestors of modern sea turtles may have come from the Deep South in the United States, new evidence suggests. Working with two relatively complete turtle skeletons, the fossils help ... read more

Sep. 30, 2016 — Different genes are involved during the adaptation of a domestic animal to life in the wild than when a wild animal becomes domesticated, concludes a new study. The results increase our understanding ... read more

Sep. 30, 2016 — Key sex-determining genes continue to operate in a mammalian species that lacks the Y chromosome, taking us a step further toward understanding sex ... read more

Sep. 29, 2016 — Animals live in close association with microorganisms, carrying beneficial bacteria while coping with pathogenic infections. Now, a study shows that symbiotic bacteria play a direct role in the ... read more
