The evolution of human bipedalism which began in primates about four million years ago or as early as seven million years ago with sahelanthropus has led to morphological alterations to the human skeleton including changes to the arrangement and size of the bones of the foot, hip size and shape, knee size, leg length, and the shape and orientation of the vertebral column. The evolutionary factors that produced these changes have been the subject of several theories.

Answer:

Charles Darwin’s study of evolution predicts that genetic evidence would show that all organisms share a common ancestor.

Option: (B)

Explanation:

Through his "theory of evolution", Darwin found that the species exist and new species form based on natural selection.
He studied the animals and birds in Galapagos island for his evolution theory.

The four key points of Darwin's Theory of Evolution:

individuals of any species are not identical;

genes are passed from one 'generation' to another;

more offspring are born than can survive;

only the 'survivors of the competition' for the resources will reproduce.

A climate zone is an area that is defined by two main factors. What are they?

MA_775_DIABLO [31]

Answer:

Temperature and precipitation.

Explanation:

Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.

Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

The disappearance of the deer from the forest indicates the EXTINCTION OF THE DEER.
The extinction of the deer from the forest will throw the ecosystem out of balance and has negative impacts on the ecosystem. After all the deer has been eliminated, the elephants too will either have to find another source of food or be wiped out.
