Natural selection 1. Differential contribution to next generation (Natural selection)  Beneficial changes are passed onto next generation 2. Variation is genetic 3. Change in genetic composition of population (evolution) 4. Individual relative contribution (fitness)  Environmental  When animals are born during a particularly good/bad time and their genes get passed on despite  their genetics Mutations Cause change in genetics When DNA is being replicated, and a pairing is mismatched like A-G instead of AT, so when  replicate again, you have AT and CG instead of having two ATs like you were supposed to from  the beginning. It is a 10^-6 or -9 mistake Point mutation: single mutation of nucleotide (AGCT) (A -> G) Insertion: Nucleotide or sequence added Deletion: Nucleotide sequence missing Duplication: Two or more copies of sequences
