Evolution Notes:

 

All living things share a common ancestor.

 

We can draw a Tree of Life to show how every species is related.

 

Survival of the Fittest- the organisms that have the best adaptations are the ones who will last.

 

Fittest- organisms best suited for their environment will survive.

 

Where food was limited, competition meant that only the fittest would survive. 

 

Genotype- In your genes; the genetic make-up of an organism 

 

Phenotype- Physical look; an organism’s genotype and the environment in which it lives determines its total characteristic traits

 

Mutation:

However, occasional mutations or copying errors can and do occur when DNA is replicated.
