ScienceDaily keeps an eye out for creepy-crawlies with news that primate vision may have evolved *specifically* to identify snakes:

In a paper published Oct. 28 in the journal Proceedings of the National Academy of Sciences, [Lynne] Isbell; Hisao Nishijo and Quan Van Le at Toyama University, Japan; and Rafael Maior and Carlos Tomaz at the University of Brasilia, Brazil; and [...]

Nature draws an ancient lesson from America’s favorite pastime, observing how baseball pitchers reveal the evolution of human beings:

“Throwing projectiles probably enabled our ancestors to effectively and safely kill big game,” says Neil Roach, a biological anthropologist at George Washington University in Washington DC, who led the work. Eating more calorie-rich meat and fat would have helped early hominins’ [...]

Nature demonstrates how (possibly) our machines are transforming birds’ whole existence:

Roadside-nesting cliff swallows have evolved shorter, more manoeuvrable wings, which may have helped them to make hasty retreats from oncoming vehicles, according to a study published in Current Biology1.

The study’s authors discovered the trend after noticing that the number of vehicle-killed birds had declined over the past three [...]

Or at least, Astrobiology says, save the species’ descendants. The secret of survival, on an evolutionary scale, isn’t a single lucky mutant, but a whole “relay team” of freaks that turn out to be pretty good at coping (and making babies) in the long run:

PhysOrg calls it “man’s remotest relative,” a living thing that has no branch on the tree of life. Why can’t they just call a shoggoth a shoggoth, man?:

The elusive, single-cell creature evolved about a billion years ago and did not fit in any of the known categories of living organisms — it was not an animal, plant, parasite, [...]

Science Mag produces proof – actual, empirical proof – that nice guys really can finish first and that even killer robots can learn to care for each other:

Laurent Keller of the University of Lausanne in Switzerland wondered if he could resolve the debate using a computer simulation. He and roboticists Markus Waibel and Dario Floreano, both from the [...]

Scientific American notices that the mosquitoes that carry malaria seem to be splitting off into their own species:

“We can see that mosquitoes are evolving more quickly than we thought,” Mara Lawniczak, of the Division of Cell and Molecular Biology at the Imperial College London and co-author of the first study, said in a prepared statement. She and her [...]

LabSpaces shares some interesting research on the role of novelty in human development:

An earlier study by Kanazawa found that more intelligent individuals were more nocturnal, waking up and staying up later than less intelligent individuals. Because our ancestors lacked artificial light, they tended to wake up shortly before dawn and go to sleep shortly after dusk. Being nocturnal [...]
