The rate of adaptive evolution in human populations has indeed accelerated within the past 80,000 years. The results above demonstrate the extent of acceleration: the recent rate must be one to two orders of magnitude higher than the long-term rate to explain the genomewide pattern.

Beneficial genetic changes have appeared at a rate roughly 100 times higher in the past 5,000 years than at any previous period of human evolution, the researchers determined. They added that about 7 percent of human genes are undergoing rapid, relatively recent evolution.
Harpending said the genetic evidence shows that people worldwide have been getting less similar rather than more similar due to the relatively recent genetic changes.

MULTIPOLAR (multipolarity)
Having or conceiving multiple centers of power or influence
http://en.wikipedia.org/wiki/Multipolar_neuron
A multipolar neuron (or multipolar neurone) is a type of neuron that possesses a single (usually long) axon and many dendrites, allowing for the integration of a great deal of information from other neurons. These dendritic branches can also emerge from the nerve cell body. Multipolar neurons constitute the majority of neurons in the brain and include motor neurons and interneurons.
A. Pyramidal cell.
B. Small multipolar cell, in which the dendrites quickly divides into numerous branches.
C. Small fusiform cell.
D and E. Ganglion cells
