Recall that Jean-Baptiste Lamarck was one of the first to study the idea of evolution systematically (p. 450 of our text) and proposed the idea of inheritance by acquired characteristics, where individuals develop phenotypes in response to environmental changes. Could it not be claimed that Lamarck was correct in his thinking with regards to our immune system? Provide one example where our immune system supports his acquired characteristics idea and one reason that it does not.

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:
