Morality has been the topic of interest since the beginning of human civilization. Through most of history discussions pertaining to the moral aspect of human nature lay in the realm of religion and philosophy. The development of scientific thought brought new tools for understanding of this phenomena and led to the question whether moral sense is part of human nature, the products of biological evolution which can be explained by applying scientific methods, rather than uniquely human asset that being given by transcendent power. Controversial discussions over ecological conservation, human r...

... , evolution gives workers a powerful way to organize the remains of past life and better understand the one history of life. Evolution is the cornerstone of modern biology. It unites all the fields of biology under one theoretical umbrella. It is not a difficult concept, but very few people have a satisfactory grasp of it. One common mistake is believing that species ... from bacteria through "lower" animals, to "higher" animals and, finally, up to man. Mistakes permeate popular science expositions of evolutionary biology. Mistakes even filter into biology journals and texts. Misunderstan...

There is no doubt that evolutionary biology will become more important as the years go on in the search for controls to all diseases. As data is collected and analyzed, ... is high time that physicians and other healthcare professionals realize the impact of ecology and evolution on health. The study of evolutionary medicine has grown out of anthropology, evolutionary biology, and population genetics. Lappe is convinced that evolutionary theory is as essential for understanding ho...

... of finch might arise in only about 200 years. Darwin's original hypothesis has undergone extensive modification and expansion, but the central concepts stand firm. Studies in genetics and molecular biology, fields unknown in Darwin's time, have explained the occurrence of the hereditary variations that are essential to natural selection. Genetic variations result from changes, or mutations, in the ... and pests, the responsible organisms have been evolving to escape our controls. Moreover, scientists can perform experiments to study evolution in real time, just as experiments are used to ...
