Jean-Baptiste de Lamarck’s explanation for the evolution of long-legged giraffes from shorter-legged okapi-like ancestors migrating to a savanna would not include which of the following features? over time, inheritance of acquired characteristics in okapis would lead to savanna giraffes once an okapi had acquired longer legs, it could pass on this new trait to its offspring only those okapis with favorable traits (long legs) could be ancestral to savanna giraffes each individual okapi could increase its leg-length by deliberate, consistent exercise okapis in a savanna habitat found it advantageous to stretch their legs for treetop leaves

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
