Four Principals of ToEbNS
1. Overproduction
2. Variation
3. adaptation/reproduction advantage
4. decent w/ modification/heritability
10
New cards
Overproduction
more offspring than can survive
11
New cards
variation
can only act on traits that exist
12
New cards
adaptation/reproduction advantage
survival of the fittest
13
New cards
decent w/ modification/heritablility
overtime, populations change as more individuals w/ particular traits survive and pass them on
