Protective Brain Hypothesis Confirmed – Larger Brains Live Longer

Large brains have been correlated with longevity in some animals. Despite many problems created by large brains such as energy consumption and birthing difficulties, species with large brains have been shown to live longer than those with smaller brains.

Where Does Our Head Come From?

New research has shed light on the evolutionary origin of the head.Researchers showed that in a simple, brainless sea anemone, the same genes that control head development in higher animals regulate the development of the front end of the swimming larvae.

How Human Language Could Have Evolved from Birdsong

Linguistics and biology researchers propose a new theory on the deep roots of human speech. A new study suggests human language is a grafting of two communication forms found elsewhere in the animal kingdom: first, the elaborate songs of birds, and second, the more utilitarian, information-bearing types of expression seen in a diversity of other animals.
