PPT-BIOLOGICAL EVIDENCE FOR EVOLUTION

The First Organic Molecules All living things consist of organic molecules How did these building blocks of life first form Scientists think that lightning sparked chemical reactions in Earths early atmosphere They hypothesize that this created a soup of organic molecules from inorganic chemicals In 1953 scientists Stanley Miller and Harold Urey used their imaginations to test this hypothesis They created a simulation experiment to see if organic molecules could arise in this way . Variation in Living Things. SPECIES  - Group of organisms that interbreed. VARIATION - small differences between individuals of a species  . Some neither helpful nor harmful  . Some enable organism to be better suited to its environment.. Chapter 10. Biological Evolution. Evolution the word, has several meanings.
