There is a universal nature to the genetic code – evidence that helps us understand how humans are part of an overall web of life on earth. Since variation occurs during meiosis, this is when errors in the copying of genetic material can create major shifts. The evolutionary significance of meiosis can be illustrated by examples of genetic variation that result from a failure of the meiotic process.
Watch these two video clips to understand the important distinction between the process of mitosis and meiosis:

Now consider a situation where the genetic code is manipulated in an entirely different way. People get excited about the topic of cloning. Like any controversial subject, there is a great deal of misinformation getting passed around. Start your research at the site listed below so we can make sure we all understand the basics.
