Spontaneous generation
Life comes from no living things
Biogenesis
Life comes from life
Redi
Flies and rotting meat
Spallanzani
Boiled broth, sealed flasks
Pasteur
Flask with opened curved neck preventing air to come in but still no life being formed
Miller Urey

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
Vestigial
No function
Related
Three records proof of evolution
Fossil
Anatomical
Molecular
Convergent evolution
Species evolve similar traits
No common ancestor
Divergent
Similar DNA
Homologous structures
Differentiate
Coevolution
Species change because of influence of others
To help each other function
Flowers and bees
Artificial selection
Humans create
