Evolution

Evolution

1. Where it all begins

   • overproduction of young
     • variation within species
       • competition between organisms
         • survival of the fittest
           • inheritance of beneficial genes
             • gradual change of species

2. Speciation = when members of a species evolve differently due to seperation and enter a new species

3. DNA

   • nucleus
     • 46 chromosones (23m+23f)
       • gene
         • DNA
         • genes are protien instructions
           • an allele is a variation of gene
