of Modern Evolutionary Theory
Populations of organisms have
New forms of life are continually
generated by the splitting of a single lineage into two or more lineages
= "speciation". "Tree of life".
Most evolutionary change
is probably driven by natural selection = individuals carrying genes that
better suit them to the current environment leave more offspring than individuals
carrying genes that make them less adapted.
