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...]
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...
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
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
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
A panel of academic booksellers, librarians, and publishers asked the public to vote on which academic book from a list of 20 is "the most influential." Charles Darwin's "On The Origin of Species" (1859) dominated with 26% of the vote,...Show More Summary
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.
Sequential divergence and the multiplicative origin of community diversity. 2015. PNAS. A parasitic wasp (Diachasma alloeum) that preys upon a fruit fly species known as an apple maggot. Researchers found that the wasp evolved afterShow More Summary
The Coalsack Nebula is located about 600 light-years away in the constellation of Crux. This huge, dusky object forms a conspicuous silhouette against the bright, starry band of the Milky Way and for this reason the nebula has been known...
Scientists investigating human and chimpanzee locomotion have uncovered unexpected similarities in the way the two species use their upper body during two-legged walking.
We can now know the original color of species that lived millions of years before humans arrived on the scene.
Chemical, experimental, and morphological evidence for diagenetically altered melanin in exceptionally preserved fossils. 2015. PNAS. Researchers discovered the reddish brown color of two extinct species of bat from fossils dating back...Show More Summary
The effects of an animal population's extinction may echo beyond the original species, new research finds. Loss of a population could ultimately result in the extinction of parasites -- which are critical for a healthy ecosystem. Researchers focused this particular study on a Brazilian fish community and their associated parasites.
The world was abuzz this week over a new human ancestor species found in South Africa. It is just the latest in a race by countries to claim the “first” example of our ancestors.
Famed British conservationist Sir Peter Scott, who gave the Loch Ness Monster the scientific name of Nessiteras rhombopteryx as part of an effort to protect it as an endangered species in case it's real, originally tried in 1960 to get Queen Elizabeth to approve the name Elizabethia Nessiae.

As a species, humans are pretty awful for the rest of the things living on this planet. But as it turns out, you can take one less creature off the extinction list: Allonautilus scrobiculatus isn’t all gone, just quite hard to find. Read more...
Screencaps via In his latest project, French artist Maxime Guyon analyzes the evolution of photography under the lens of “exaptation”, a term originally relating to an evolutionary phenomenon, where one trait of a species shifts toward a new and different function as it evolves further.

The original illustration of Stygophalangium karamani, from Oudemans (1933). In 1933, the Dutch zoologist Anthonie Oudemans described what he believed to be a remarkable new species of harvestman. Based on two specimens collected from...Show More Summary
Even just a few years ago, it seemed like science fiction was an endangered species on television. But now, there’s a new wave of smart, ambitious science fiction coming to the small screen. And meanwhile, a lot of original SF has flopped at the movies. Read more...
There is considerable debate over the origin and ongoing role of post-reproductive life span in evolution. If evolution is driven by reproductive success, why do the individuals of some species live on far past the capacity to reproduce?...Show More Summary
