Carlos Linneaus
Linneaus was a Swedish physician and botanist who sought to classify life's diversity. He laid the foundations for the modern biological naming scheme of binomial nomenclature. -
Hutton
Hutton was a Scottish geologist, physician, chemical manufacturer, naturalist, and experimental agriculturalist. He proposed the Earth's geologic feature could be explained by gradual mehcanisms currently operating in the world. -
Cuvier
Cuvier was a French Scientist who studied palentology, the study of fossils. He noted that the older the strata was, the more dissimilar the fossils are from current life. HIs studies of the strata established the basic prinicples of biostratigraphy. He also established extinction -
Darwin
In 1838 Charles Darwin made his theory of natural selection which is the differential success in the reproduction of different phenotypes resulting from the intereaction of organisms with their environment. Then in 1871 he examined human evolution. Darwin is known worldwide for his theory of evolution which is the change of human bodies over time. -
Gregor Mendel
Gregor Mendel's experiments of certain traits in pea plants led to the study of heredity. Around 1854, Mendel began his research on the transmission of hereditary traits in plant hybrids. Mendel chose pea plants becasue of their many distinct varieties and offspring could quickly and easily be produced. -
Avery-Macleod-McCarty
In 1944 Oswald Avery, Colin Macleod, and Maclyn McCarty reported an experiment that DNA is is the substance that causes bacterial transformation. They started the experiments in the 1930's and it went through the 1940's. The purpose of this experiment was to purify and characterized the "transforming principle" responsible for the transformation phenomenon. -
Franklin
Rosalind Franklin was an Englsih Chemist and crystallographer that made criticcal contributions to the understanding of the molecular structure of DNA. Her work achieved the most profound impact as DNA plays a central role in biology. Her work carriers the genetic information that is passed from parents to their offspring. -
Hershey-Chase
The Hershey and Chase experiments were conducted in 1952 by Alfred Hershey and Martha Chase. Their experiment was to confirm that DNA is the genetic material. They showed that when bacteriophages infect bacteria that their DNA enters the host bacterial cell but most of their protein doesn't. Their results were not conclusive but their discoveries served to prove that DNA is the hereditary material. -
Watson and Crick
Watson and Crick won the 1962 Noble Prize in Medicine. They won for their discovery of the struture of DNA. February 28th, 1953, was when they determined that the structure of DNA was a double helix polymer. -
Wilkins
Wilkins was a British biophysicist that was best known his contributions to the structure of DNA discovery. He created the X-Ray images. He was jointly awarded the Noble Prize with Crick and Watson in Physiology and Medicine in 1962. -
Lyell
Lyell was a British lawyer and the foremost geologist of his day. He proposed that the same geologic processes are operating today as in the past, and at the same rate.
