Document Summary

Chapter 2: origins of the human brain and behaviour: cladogram: a graph that shows the relative time of origin of various closely related groups. Hominids were taller, and there was less difference in height between males and females. Similar genes, called homeobox genes, dictate body segmentation in both fruit flies and humans. Thus, segmentation of the human nervous system into the spinal cord, brainstem, and forebrain is produced by genes first discovered in fruit flies. The symptoms include rigidity that impedes voluntary movement, balance problems, and tremors of the head, hands, and limbs. The cause of parkinson"s dis-ease is unknown, however, and there is no cure: quasi- evolutionary sequence, a hypothetical sequence of animals that represent consecutive stages in evolutionary history. Genes are segments of dna that specify what proteins a cell should make. Each gene is a long chain of four kinds of nucleotide bases.
