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
Origin of the blogging species
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
From the Extropians to Seasteaders and everyone in between
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
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
These 14 mammals were in the first class of endangered species
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
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
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."
When it first announced its upcoming subscription service SeeSo, NBCUniversal announced a number of live comedy specials to complement the TV shows and original programs it plans to distribute to subscribers. Now, one of those specials is ready to go. Show More Summary
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.
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.
