Life Encourages Variety by Recombining Information

Recombining Instructions

• Nature creates new combinations by recombining
  information.
• Bacteria and DNA injection.
• Sexual Reproduction as information mixing.

Recombining Instructions

• Recombining Information is like lining up two
  long chains of information from two individuals
  and randomly cutting them and exchanging pieces
  and then passing a mixed chain to the next
  generation.

4
Recombining Instructions

• The longer the chains, the more possibilities for
  the information to exchange.
• 10 crossing with 10 1233 possible combos
• 12 crossing with 12 4086
• There are 70,000 genes!!!
• The number of possibilities is staggering.

5
Having It Your Way with Genes

• With generation after generation of information
  mixing, changes in genes accumulate and the
  appearance or function of succeeding generations
  of a living organism can change dramatically.

6
Having It Your Way with Genes

• In nature, changes in genes arise from accidental
  alterations mutations and from the exchange
  of genetic information when organisms reproduce.
• With each alteration of the information that
  specifies their form and function, creatures
  become better or worse suited to their
  environment.

7
Having It Your Way with Genes

• The better suited tend to survive and reproduce (
  to mix and pass on their genes again).
• Gene reshuffling creates diversity, causing
  animals of the same species to come to vary
  greatly in appearance.
• Some humans have taken to coordinating this gene
  shuffling.
