Characteristics of first life forms
Autotrophs
No light, chemosynthesis
Prokaryote
Two types of autotrophs
Photo autotrophs - light
Chemo autotrophs - chemicals
Endosymbiosis
Large prokaryote combines with small
Darwin
Animals have traits that will help them survive not by need
Lamarck
Develop needs and wants and pass to offspring
Natural selection
Those with good traits will survive
Why is variation needed
Species would never evolve, no natural selection
Different animals of same species will be different
Homologous
Originated by heredity
Same parts on inside
Analogous
Aren’t related
Same purpose
Different insides
