Science: Colleen Cavanaugh
Dr. Cavanaugh is a Professor of Biology in the Department of Organismic and Evolutionary Biology at Harvard University. Cavanaugh’s research focuses on the ecology and evolution of bacteria, with special emphasis on symbiotic bacteria, which is associated with marine invertebrates that inhabit deep-sea hydrothermal vents and shallow reducing sediments. Cavanaugh’s studies showed the major macrofauna at hydrothermal vents studied to date host symbiotic, chemosynthetic bacteria. These bacteria use ...
Science: Darwinism
In the 1930s and 1940s, neo-Darwinian synthesis or neo-Darwinism appeared. The theory gave a new look at Darwinism theory. It proved that genetic variations in populations are the result of mutation and recombination. Evolution between one generation and another is a result of genetic drift, gene flow and natural selection. When populations are isolated by geographic barriers the process occurs gradually. The discovery of DNA caused those statements. It proved that the evolution of species happe ...
Science: Genetic Testing
What is genetic testing? Genetic testing is widely used by the modern medicine to find out whether the person has a genetic precondition of disease or whether he is likely to get such a disease. Genetic issues are often related to the themes of bioethics, human decision making and moral and legal issues. Genetic issues are often discussed in relation to ethical aspects, which seem to be mutually contradictory. Is society justified in insisting that people submit to genetic screening, counseling ...
