Evolutionary forces

Topic: Biology , Human

Evolution is the biological context is the process that alters the organisms under extremely long time periods. From generation to generation. As an example of evolutionary forces, I take the beaver. Today's bävrars grandfather, grandfather, great grandfather, grandfather, great grandfather, grandfather, great grandfather ... etc. (Thousands of beaver generations anyway) Today beavers do not look exactly like the beavers for one hundred thousand years ago. The differences are not so great but maybe beaver teeth less or tail less. It is difficult to know the difference. But go further back, one million years maybe, you can probably find even greater differences. View schoolwork »
