The Evolution of the Human Brain: How it Differs From Our Ancestors and Why? The human brain is a feat of evolution: it has allowed humans to have complex thoughts‚ conscience‚ build tools‚ create fires‚ and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors‚ including apes‚ had very small brains‚ but as evolution progressed‚ so too did the human brain. The rapid progression

Essay on Evolution There are many mechanisms that lead to evolutionary change. One of the most important mechanism in evolution is natural selection which is the differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Natural selection occurs when a environment makes a individual adapt to that certain environment by variations that arise by mutation and genetic recombination. Also it favors certain traits in a individual

by the United Nations Convention on Biological Diversity‚ it includes diversity of ecosystems‚ species and genes‚ and the ecological processes that support them. Natural diversity in ecosystems provides essential economic benefits and services to human society—such as food‚ clothing‚ shelter‚ fuel and medicines—as well as ecological‚ recreational‚ cultural and aesthetic values‚ and thus plays an important role in sustainable development. Biodiversity is under threat in many areas of the world. Concern

I read through many books and sources to help make the history of language a little more clear and found many interesting ideas. I found that something as simple as the way you use your hand could shape the brain‚ language‚ and human culture (The Hand). I also found many sources on human evolution; and digging a bit deeper into this area showed me many thoughts and
