On the origin of Eukaryotes -- when cells got complex

Just as physicists comprehend the origin of the universe by observing the stars and archeologists reconstruct ancient civilizations with the artifacts found today, evolutionary biologists study the diversity of modern-day species toShow More Summary

Phytoseiids and the Importance of Taxonomy

Gupta's (1975) original figures for Amblyseius syzygii. For this week's semi-random post, I drew the mite species Amblyseius syzygii. Or perhaps that should be Typhlodromips syzygii, as it's more likely to be designated now. Typhlodromips syzygii is a member of the Phytoseiidae, a diverse family of about 1600 known species of predatory mite. Show More Summary

The origins of abiotic species

Researchers are studying a 'chemical evolution' to see if self-organization and autocatalysis will provide the answer. This research group previously developed self-replicating molecules -- molecules that can make copies of themselves -- and have now observed diversification in replicator mutants. Show More Summary

The origins of abiotic species

How can life originate from a lifeless chemical soup? This question has puzzled scientists since Darwin's 'Origin of species'. University of Groningen chemistry professor Sijbren Otto studies 'chemical evolution' to see if self-organization and autocatalysis will provide the answer. Show More Summary

Scientists say face mites evolved alongside humans since the dawn of human origins

A landmark new study explores the fascinating, little-known natural history of the face mite species Demodex folliculorum, using genetic testing to link the microscopic animal's evolution to our own ever-evolving human story. By zooming...Show More Summary

Tramp ant caught globetrotting under false name

A century-old mystery surrounding the origin of an invasive ant species was recently solved by an international team of scientists. Since 1893, when it was first discovered as an invasive species in the Canary Islands, entomologists have been debating where this mystery species came from. Show More Summary

Atheists Call for 'Bible-Free' Hotel Rooms, Want Darwin's 'On the Origin of Species' Instead

The Freedom from Religion Foundation, America's largest association of atheists and agnostics, began a campaign Monday to rid all hotel rooms of Bibles distributed by The Gideons International and replaced with copies of Charles Darwin's "On the Origin of Species."

New sand fly species discovered in Brazil

Researchers in Brazil examined sand fly specimens in museum collections. After detailed analyses of three different flies in the genus Psathyromyia, they found that the specimens were originally misidentified and that they were actually an undescribed species.

Christians on Twitter Are Complaining About Today’s Evolution Google Doodle

If you’ve been on Google today, then you’ve seen the doodle marking the 41st anniversary of the discovery of Lucy, a set of fossils that helped us understand our species’ own origins: As predicted yesterday, some Christians on Twitter are already complaining about how this is some sort of assault on their faith: @google my [Read More...]

Origin of Earth's First Species --A New Theory

During the earliest evolution on earth, life probably resembled one big genetic jumble. At some time, presumably around 3.8 to 3.5 billion years before today, the very first biological species appeared – the ancestor of all life forms that developed...

Evolution Is Finally Winning Out Over Creationism

Few issues have divided the American public as bitterly as Charles Darwin’s theory of evolution by natural selection. Since On the Origin of Species was published in 1859, it has driven a wedge between those who accept that humans and...Show More Summary

Mammoth Evolution and Dispersal Across the Northern Hemisphere

Evolution and dispersal of mammoths across the Northern HemisphereAuthors:Lister et alAbstract:le of species origins and dispersal, but understanding has been impeded by taxonomic confusion, especially in North America. The Columbian mammoth Mammuthus columbi was thought to have evolved in North America from a more primitive Eurasian immigrant. Show More Summary

Fossils tell a different ancestral story of North American mammoths

A detailed analysis of mammoth teeth from around the globe suggests that the first mammoth species to arrive in North America was much more evolved than previously thought. While the evolutionary origins of Eurasia's mammoths are established, much less is known of Columbian mammoths, the species that later resided in North America. Show More Summary

Link between small mammals and evolution of hepatitis A virus to humans discovered

Researchers have found a link between the origin of hepatitis A virus (HAV) and small mammals. With the emergence of Ebola virus from bats and hantaviruses from rodents, investigators say identifying the other species infected with HAV provides novel insight into the evolution of HAV and how it spread to humans.
