Evidence for Evolution Flashcards

All 4 cards in this deck

What two types of evidence are used to support the theory of evolution?: Fossils and antibiotic resistance in bacteria.
How does the fossil record provide evidence for evolution?: It shows how organisms have gradually changed over millions of years.
True or false? Antibiotic resistance in bacteria is evidence of evolution happening now.: True. Bacteria reproduce very quickly, so natural selection of resistant strains can be observed over a short time.
Apart from religious objections, give two reasons why Darwin's theory was only gradually accepted.: There was not enough evidence at the time to convince many scientists, and the mechanism of inheritance and variation was not known until 50 years later.
