The Paris Peace Treaties
1,644 wordsThe Paris Peace Treaties (1919 - 1920) IB History To the subject and passive onlooker, those meticulous organizers of the Paris Peace Treaties allowed for an unfortunate amount of flaws to enter their task of creating a treaty that could satisfy all of the nations of not only Europe but of the world as well equally. Yet one must attempt to put that passiveness behind and admit that those of the time of post World War I had truly no idea what was to come of their decisions. Thus, the decisions of...

The most major breakthroughs of the century in science has occurred and we are not ready for it. The scientific breakthrough of cloning has caused a great deal of controvers...

Cultural Evolution Cross Cultural
1,119 wordsIn the middle of this century, both biological and cultural anthropology experiences a major change in theory. In biological anthropology, biological anthropologists adopted an approach which focused on the gene. They saw the human evolution as the process of genetic adaptation to the environment.

In the field of anthropology, a very important theory is that of the sociobi...

Genetic Drift Antibiotic Resistance

Biological And Cultural Adaptive Radiation Erectus
457 wordsAbout one million years ago, Homo erectus populations began migrating out of East Africa. They soon spread into South and West Africa, Asia and Europe. This adaptive radiation was the result of several biological and cultural factors. H. erectus was physically larger than earlier hominids. This probably allowed them to fun faster and further than their ancestors and could have given them an advantage in hunting and escaping. It may also have increased their food gathering abilities by expanding ...
