Dinosauroids - Color test

The Dinosauroids is a fascinating concept being explored by artist Simon Roy (deviantART, Blogger, tumblr) based on the premise that the dinosaur-killing Chicxulub asteroid misses Earth:

However, the resulting world is not simply a long-lived cretaceous paradise – the Deccan Traps still flooded the sky with ash and changed the climate and atmosphere, killing off most, if not all, of the great dinosaurs. The survivors of such an event, however, are a handful of small therapods, mammals, birds, and even a few pterosaurs.

While our ancestors developed the hand-axe and honed their stone-throwing skills to scavenge kills, the saurian’s ancestors were developing more and more advanced pointy sticks.

The Dinosauroids

The Dinosauroids is a fascinating concept being explored by artist Simon Roy based on the premise that the dinosaur-killing Chicxulub asteroid misses Earth, but the changing climate still wipes out most of the great dinosaurs leaving the world to a handful of small therapods, mammals, birds, and even a few pterosaurs.

Crows’ reasoning ability rivals that of seven-year-old humans

Using the Aesop’s Fable Paradigm to Investigate Causal Understanding of Water Displacement by New Caledonian Crows:

Understanding causal regularities in the world is a key feature of human cognition. However, the extent to which non-human animals are capable of causal understanding is not well understood. Here, we used the Aesop’s fable paradigm – in which subjects drop stones into water to raise the water level and obtain an out of reach reward – to assess New Caledonian crows’ causal understanding of water displacement.

We found that crows preferentially dropped stones into a water-filled tube instead of a sand-filled tube; they dropped sinking objects rather than floating objects; solid objects rather than hollow objects, and they dropped objects into a tube with a high water level rather than a low one.

However, they failed two more challenging tasks which required them to attend to the width of the tube, and to counter-intuitive causal cues in a U-shaped apparatus. Our results indicate that New Caledonian crows possess a sophisticated, but incomplete, understanding of the causal properties of displacement, rivalling that of 5–7 year old children.
