We know that <span>is evidence that supports assimilation and multiregional evolution models for modern human evolution. This multiregional evolution is an hypothesis based on a scientific model that is in itself an alternative explanation o human evolution. Part of this claims that the neandertals can be accepted as homo sapiens which is widely debated by many of the scientist. </span>
3) is active transport because active transport requires energy.
