What Did Charles Darwin Observe In Galopagos Islands Fhat Proves Evolution Flashcards
Species vary globally
Distinctly related species Living in similar habitats in different parts of the world look and act similar. Suggested common ancestor When continents were together ( Pangea), eg large flightless birds live in grasslands on different countries
Species vary locally
Related animals that occupy different habitats within a local environment have different features. Example, finches in different islands have different beak sizes based on the size of seeds on each island
Species vary over time
Darwin found fossil evidence of species changing over time
What is Darwin’s theory
All species of organisms living on earth today are descended from ancestor species. Species evolve over time. Natural selection is the mechanism causing species to evolve
