Crows are no bird-brains: Neurobiologists investigate neuronal basis of crows' intelligence -- ScienceDaily
yuiami 2013/12/08
Crows manage to memorize a target shape and recognize some rules of the game to follow. One time the rule is "choose a shape of the same category," the other time "choose a shape of a different category." Crows handle with both types of rules.

Children, not chimps, prefer collaboration: Humans like to work together in solving tasks -- chimps don't -- ScienceDaily
yuiami 2012/06/10
Comparison between 3yo children and chimps. They were to solve the task (pulling two ends of a rope to get a reward) together or alone. 78% of human children cooperated while chimps did in 58% of the time. They plan to include the bonobos (which have been said to have motivation for cooperation).

Salamanders spell out evolution in action -- ScienceDaily
yuiami 2011/07/09
A salamander "ring" species. In the middle of the "ring" there is fairly active hybridization, while there is little at the ends of it. Researchers see it as showing that genetic incoherence is the key factor for reproductive isolation, not different ecological niches

Formally believed that Neanderthals' diet is specialized on a couple of particular foods while early humans' diet was more diverse, which is partly the reason of N's extinction. But found that N's diet was as diversified as human's. Thus this is evidence against the hypo above.
