Key Info
  • Evolution of life on Earth
  • Duration: 01:49
  • An introduction to evolution from the cloning of early single-celled organisms to sexual reproduction, which has led to the formation of more recent and complex animals and plants. The cell is introduced as the first life. We see cells dividing in the process of asexual reproduction, which is described as cloning. Images of sperm, eggs and sexual reproduction are then shown. This is described as the catalyst for the huge diversity of life we currently have on Earth. Explains that sexual reproduction and chance have led to the evolution of man.

Order them from those you think are the most evolved to those you think are the least evolved. The clip lends itself very nicely to reviewing this at the end.
