GEN BIO - THEORIES OF EVOLUTION

He developed the MODERN TAXONOMIC SYSTEM that is still used today

Carl Linnaeus (1707-1778)

established the modern concept of a species, noting that members of one species do not interbreed with member of another species. HE FIRST USED THE TERM “SPECIES” as the basic unit of taxonomy.

John ray (1627-1705)

wrote a 36-vol Histoire Naturelle (Natural History)

He contributed to the debate on the age of EARTH, suggesting that our planet had initially formed in a molten state and its gradual cooling must taken far longer than 70 000 years.

George Louis Leclerc, Comte de buffon (1707-1788)

He believed that the offspring inherited features from their parents, and that the organisms today descended from a common ancestor.

Erasmus DArwin (1731-1802)

His studies about fossils contributed and gave rise to the science of paleontology.

He recognized that particular groups of fossil organisms were associated with certain rock stratal.

Georges Cuvier (1769-1832)

He proposed the theory of use and disuse, which stated that organisms develop their traits due to the frequent use of such.

Jean-Bastiste Lamarck (1744-1892)

made a significant contribution regarding the understanding of the geological processes that shaped Earth. He recognized that Earth is extremely old (more than mil of years)

was proponent of uniformitarianism, which states that the present geological features of Earth are the results of gradual processes such as erosion and sedimentation.

James Hutton (1726-1797)

also collected many pieces of evidence to support the principle of UNIFORMITARIANISM and wrote them in his book Principles of Geology, which was also influential to the creation of charles Darwin’s theory.

Charles Lyell (1797-1875)

one of his highlighted contributions was the development of his theory of evolution by natural selection as a coherent explanation for the for

distribution of species in different locations

Charles Robert Darwin (1809-1882)

made an independent study on the origin of organisms

has contributed to some of the postulate of darwin’s theory of evolution

Alfred Russel Wallace (1823-1913)
