In today’s lesson, we are going to be focusing on biological evolution.
Biological evolution refers to the type of change that takes place within living organisms over long periods of millions of years. Biological evolution means that: All modern-day life forms descended or arose from and are re...

In our last lesson, we introduced evolution by natural selection. Today we are going to be looking at multiple theories, the basis of these theories, and the scientists behind these theories.

In today’s lesson we look at artificial selection. Artificial selection is the scientific term used to describe the breeding of plants and animals for desirable characteristics and not necessarily those that would allow the offspring to survive better. And since particular desirable characteristi...

In this lesson we will be discussing speciation and the different methods of reproductive isolation.

Welcome to our first lesson on human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioural traits shared by all people originated from apelike ancestors and evolved over a period o...

In this lesson we will look at the cultural and genetic evidence to show how similar or different humans are to African apes.

In this lesson we will be tracing the appearance and characteristics of different organisms as evidenced by fossil finds.

This lesson looks at Homo species and our historic fossil sites.

In this lesson we are going to look at some of the contributions made by these scientists. We will also have a look at the out of Africa hypothesis and the evidence used to support it.

In this lesson, we look at the arguments and alternative theories for the diversity of life.
