Sentences with word «encephalization»

Humans have the highest encephalization quotient (EQ) on the planet.

[ii] Compared to our primate cousins, humans have a much smaller gut and yet characteristically larger brains (i.e. a higher encephalization quotient).

Comparative analysis of encephalization in mammals reveals relaxed constraints on anthropoid primate and cetacean brain scaling.

Marino took a teaching job at Emory University, becoming an expert in dolphin and whale brain anatomy along with a technique called encephalization: calculating the ratio of an animal's brain size to its body size and correlating that with its intelligence.

Deaner, R. O., Isler, K., Burkart & J. & van Schaik, C. P. Overall brain size, and not encephalization quotient, best predicts cognitive ability across non-human primates.

The researchers found that cetacean encephalization is predicted by both the species» social structure and group size.

There is then a feedback loop, where these behaviors tend to promote encephalization.

Researchers have wondered why encephalization — brain expansion — evolved in some animals but not others.

He eventually came up with a complicated scheme in which all animals had a certain degree of encephalization, which increased in jumps of two (so humans were 1, apes were 1/4, cats and dogs were 1/8, etc.).

Scientists first proposed a relation between social living and brain expansion, or encephalization, nearly three decades ago, when they observed that primate species with larger brains typically lived in bigger groups.

In support of that claim, one widely cited study found that the ratio of brain volume to body mass — commonly referred to as the encephalization quotient, or EQ — was the same for Cro - Magnons as it is for us.

Intelligence is hard to quantify in humans or animals, but the encephalization quotient (EQ), a ratio of an animal's observed brain size to the expected brain size given the animal's mass, correlates well with an ability to navigate novel challenges and obstacles.

As you'd expect from the above data, the encephalization quotient (a measure of brain size compared to body size) for the Dmanisi hominids and the Turkana Boy is well below that of modern humans (6.3):

Combining cranial and postcranial dimensions, the encephalization quotient for the Dmanisi individuals is in the range of 2.6 to 3.1, which is at the lower end of estimates for KNM - WT 15000 (2.7 - 3.8) and more comparable to H. habilis (3.1) and australopiths (2.4 - 3.1).
