Carolus Linnaeus
Developed a cassification system for all types of organisms known at the time. This method grouped all types of organisms by their similarities; moreover, it refelcted their evolutionary relationship. He came up with the concept of "species"
-it iis a group of organisms so similar to one another that they can reproduce have fertile offspring(Holt Biology, 2012). -
George Louis Leclerc de Buffon
Proposed that species shared ancestors instead of arising separately. He denied the current idea that Earth was only 6000 years old; he thought it was much older. -
Erasmus Darwin
Proposed that all living things were desended from a common ancestor and hat more-complex form of life arose from less-complex forms. This thesis would be developed more deeply by his son, Charles's Darwin((1809~1882). -
Jean-Baptise Lamark
Proposed all organisms evolved toward perfection and coplexity. He reasoned that they must have evolved into different forms. He proposed that changes in an environment an organism's behavior to change, leading to ccreater use or disuse of a structure or organ, and organisms would pass on these changes to its offspring. These ideas were known as the inheritence of acquired characteristics. -
Charles Darwin
Came up with the concept of variation and adaptation from the five-year journey in Paciic islands. He observed the animals and plants which are in the same species but evolved diffently, and proposed they adapted Galapagos tortoieses and finches are the representative example of his findings.
