Regarding the evolution of the mammalian inner ear, the above diagram shows: A) the co-option of jaw bones (colored) for use in hearing B) the loss of jaw bones (colored) and the origin of de-novo hearing bones C) the evolution of synapsids, which have little to do with mammalian evolution D) the results of a population bottleneck which led to the fixation of odd alleles for ear development

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:
