Theories about humankind and the origin of life One of the earliest Greek philosophersThales of Miletus c. Biology began to quickly develop and grow with Anton van Leeuwenhoek 's dramatic improvement of the microscope. Harvey was also interested in embryology, to which he made a significant contribution by suggesting that there is a stage the egg in the development of all animals during which they are undifferentiated living masses.
In the enlarged image it is clear that the blood is all contained within little tubes. For their work they received the Nobel Prize award in Research into the origin of life, abiogenesisamounts to an attempt to discover the origin of the first cells. The most famous of the new centres of learning were the library and museum in Alexandria.

The academies also provided freedom of expression, which, together with the stimulus of exchanging ideas, contributed greatly to the development of scientific thought. Blood, he shows, does not drift in the body in any sort of random ebb and flow.
Understanding the structure and function of cells is fundamental to all of the biological sciences. He is best known to the general public for showing how to stop milk and wine from going sour - this process came to be called pasteurization.
The organism, then considered the fundamental unit of life, is still the prime concern of some modern biologists, and understanding how organisms maintain their internal environment remains an important part of biological research.
Especially important are his History of Animals and other works where he showed naturalist leanings, and later more empirical works that focused on biological causation and the diversity of life. These words persisted in the medical literature for centuries, a testament to the lengthy popularity of the idea of humoral influences.
However, anti- vitalist experimental physiologists and embryologists, especially in Europe, were increasingly influential. Alchemists subjected organic matter to chemical analysis and experimented liberally with both biological and mineral pharmacology.
Like Aristotle, Theophrastus was a keen observer, although his works do not express the depth of original thought exemplified by his teacher.
The phenomenon of diversity has had a long history of study because so many of the variations that exist in nature are visible to the eye. Human survival depended upon the accurate recognition of nonpoisonous food plants and upon an understanding of the habits of dangerous predators.
Ancient and medieval knowledge[ edit ] See also:The Greek philosophers, voracious in their curiosity, look with interest at the range of living creatures, from the humblest plant to man himself. A Greek name is coined by a German naturalist in the early 19th century for this study of all physical aspects of natural life - biology, from bios (life) and logos (word or discourse).

Taken together, the fossils fof ancient organisms make up the history of life on Earth called the fossil record. The History of Biology however, focuses on the advent of life on earth, right from the ancient times. Biological discoveries have a remarkable impact on the human society.
Traditionally, the history of biology is diversified into two wings – studies on medicine and theories of natural history/5(14). The term population biology is often used interchangeably with population ecology, although population biology is more frequently used in the case of diseases, viruses, and microbes, while the term population ecology is more commonly applied to the study of plants and animals.
Ecology draws on. Evolution through natural selection was to become one of the conceptual pillars of a unified biology and its most powerful explanatory instrument.
