People were in holes between branches, not in the main ground, recommend this study |Introduction

Although our fathers are now applicable to survive, but also lived in anger and revealed something.

Do human ancestors drive from trees?The problem was for a long time during the heavy wave of human evolution in the west.

"For large monkeys, moving in both trees and earth, important to move

The effect of shape trees

Clark and his team closely watched the chimpanz of the Valley of Issa for five months at the dry station.

The results were averaged 20 minutes to eat all the time in the trees, and parasitic plants such as Pyrostil and Legumes.

In addition, they discovered that the larger the tree and the richer the food, the longer the chimpanzees were, and that the roofed trees tended to promote longer staying with seeds and green fruits.It is known that it begins with an effective food strategy: limited trees in the environment, tree frequency, tree frequency, tree frequency, frequency of trees, frequency of trees, frequency of trees, maximizing feed consumption.

Researchers believe that the reason why large monkeys, such as Chimpanzies, began to be hanged in the trees depending on changes that they use.Facts are that the stakeded space was always monitored on the trees with Sambrella -SSultses.In the Ralos forest in the ISSA Valley, trees in the previous lab of the past, formerly the illegal that the teaching was to the end of the branches.

Intelligent update for the environmental changes

The behavior of chimpanzees observed in this study clearly demonstrates the ability of modern monkeys to maintain half-tide behavior, for example, to move in trees and soil even in open environments.This result supports the first surviving human beings, maintaining the ability to climb trees.The main adaptive strategies of our ancestors in the face of environmental changes in Savannah.

However, the research group shows that this study represents restrictions.The capacity was limited to the behavior of chimpanzees in the dry time, and it is not known whether we notice the same trends in the rainy season.In addition, researchers have only observed one group.In future studies, it is necessary to determine whether similar behaviors are observed in the primates of other regions.Hypotheses.

Nevertheless, the vision of the chimpanzees living in the plow and forest environment mosaic provides an attitude of human life millions of years ago.At least simple explanations that people have become bipartisan because they land out of the tree can no longer be valid.
