WebA) natural selection is unimportant as a mechanism of evolution. B) given enough time, most existing species will branch gradually into new species. C) most new species accumulate their unique features relatively rapidly as they come into existence, then change little for the rest of their duration as a species. WebMove down the phylogeny to where your fruit fly twig is connected to the rest of the tree. That branching point, and every Speciation is a lineage-splitting event that produces two or more separate species.
