But because the descriptions of many of the animals were grossly inaccurate, in many cases continuing the legends of the Greeks, apart from their aesthetic value the books did little to advance zoological knowledge.

A form of electromagnetic radiation with an extremely short wavelength that is produced by bombarding a metallic target with electrons in a vacuum.

Biochemistry Facts

Taxonomy has been based on two major assumptions: If substances have medicinal properties, they are considered pharmaceuticals. For example, they not only used the silkworm Bombyx mori to produce silk for commerce but also understood the principle of biological controlemploying one type of insect, an entomophagous insect-eating ant, to destroy insects that bored into trees.

Throughout the 16th century, interest in botanical study also existed in other countries, including the Netherlands, Switzerland, Italy, and France. We have determined the cryo-electron microscopy structures of an MNV virion and the virion in complex with neutralizing Fab fragments and the atomic structure of the neutralizing antibody.

With the emergence of the Greek civilizationhowever, those mystical attitudes began to change.

Although Aristotle recognized that species are not stable and unalterable and although he attempted to classify the animals he observed, he was far from developing any pre-Darwinian ideas concerning evolution. 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.

A machine that spins at an extremely high rate of speed and that is used to separate tiny particles out of solution, especially to determine their size. The ruins at Mohenjo-daro have yielded seeds of wheat and barley that were cultivated at that time. Their well-preserved mummies demonstrate that they had a thorough understanding of the preservative properties of herbs required for embalming; plant necklaces and bas-reliefs from various sources also reveal that the ancient Egyptians were well aware of the medicinal value of certain plants.

It is clear, therefore, that much of the history of biology predates the time at which humankind began to write and to keep records. The ability to apply information discovered in physics to the study of living things led to the development of the electron microscope and ultracentrifuge, instruments that have revealed important information about cell structure and function.

Aristotle described sperm and ova and believed that the menstrual blood of viviparous organisms those that give birth to living young was the actual generative substance. To better understand how it concentrates CO2, we determined the atomic structure of the bicarbonate binding protein, CmpA. Techniques for keeping organs alive in preparation for transplants stem from such experiments.

Post-Grecian biological studies With Aristotle and Theophrastus, the great Greek period of scientific investigation came to an end. Like his Greek predecessors, he believed in spontaneous generation; he also believed that animals were more perfect than plants, because they required two individuals for the sexual act.

While the enzyme is found in all organisms, this regulation is only found in the animal form. Anaximandera student of Thales, did not accept water as the only substance from which living things were derived; he believed that in addition to water, living things consisted of earth and a gaslike substance called apeiron, which could be divided into hot and cold.

Three types of natural selection, showing the effects of each on the distribution of phenotypes within a population. Biological expeditions added to the growing body of knowledge of plant and animal forms and led to the 19th-century development of the theory of evolution.

Although Anaximenesfor example, who may have been a student of Anaximander, adhered to the then-popular precept that life originated in a mass of mud, he postulated that the actual creative force was to be found in the air and that it was influenced by the heat of the Sun.

Another source of information concerning the extent of biological knowledge of these early peoples was the discovery of several papyri that pertain to medical subjects; one, believed to date to bce, contains anatomical descriptions; another c. An example of the relationship between those two factors was the discovery of the cell.

As part of a larger DARPA project, we have been using a variety of methods to predict what kinds of mutations in the virus could lead to escape from antibody neutralization with the hope to extrapolate these findings to other virus systems that have more lethal pandemics.

Other schemes that have been used for grouping species include large anatomical similarities, such as wings or fins, which indicate a natural relationship, and also similarities in reproductive structures.

His careful examination of animals led to the understanding that mammals have lungs, breathe air, are warm-blooded, and suckle their young.

Physics (PHYS)

Moreover, as a result of the relatively recent development of extremely sophisticated instruments, such as the electron microscope, the ultracentrifuge, and automated DNA sequencing machines, biology has moved from being a largely descriptive science—one concerned with entire cells and organisms—to a discipline that increasingly emphasizes the subcellular and molecular aspects of organisms and attempts to equate structure with function at all levels of biological organization.
