animals Researchers based in the U.S. and Sweden who analyzed evolutionary change in groups of primates found the numbers of males lags behind females. The number of females in a group tends to be larger than the number of males; the more than females there are the more males there will be, precisely only after a period, when the males have had time to pull in up to the changing population. As mixed-sex, multi-male groups are common in more advanced primate societies (including humans), scientists say the study highlights the immenseness of females in understanding social evolution.

The time lag surrounded by numbers of females and males was revealed using a family tree (or phylogenetic tree), with respective(a) branches showing relatedness between species. "A simple example is the human relationship between us and chimps which looks like a V," said Patrik Lindenfors, a zoologist at the University of Virginia, Charlottesville. "Chimps are on one exploit of the V, with us on the other, and o...If you want to get a copious essay, order it on our website: Orderessay
