Nasīr al-Dīn al-Tūsī
Developed a little theory about evolution in which he stated that organisms gained differences through adaptations to their environments. He describes these differences as beneficial towards the organism getting these differences. -
Carolus Linnaeus
This botanist developed the modern-day hierarchical classification system, In which we use to determine the naming of organisms -
Erasmus Darwin
Proposed the idea that all warm-blooded organisms arose from one single form, and proposed the idea of natural selection -
Jean-Baptiste Lamarck
printed out his own theory of evolution in which it stated that evolution happens through the inheritance of acquired features. He also thought that environmental change can lead to the use or disuse of internal or external structures for an organism -
Charles Darwin
Charles Darwin set off on his voyage on the HMS Beagle, and along this journey, he analyzed and collected species; He made important discoveries on this journey which made him come up with the theory of evolution. -
Alfred Russel Wallace
Alfred Russel Wallace publishes his own theory of evolution and connects it to natural selection; Charles Darwin was sort of his partner in this theory as well. -
Charles Darwin
Darwin publishes his book, On the Origin of Species, and this book contains the fundamental ideas of his theory of evolution; this book becomes very popular -
Gregor Mendel
Mendel publishes his paper work on his experiments with pea plants and lays a layout for the laws of genetics. -
DNA structure discovered
Cricket, Watson, and Franklin discover the structure of DNA and notice that that the structure meets the unique requirements for genetic "coding" -
mRNA discovered
mRNA is discovered, and could be used to further prove the idea of evolution! -
"Lucy"
"Lucy", the remains of an Australopithecine female, is found at Hadar, further proving evolution -
Charles Sibley and Jon Ahlquist
These two people demonstrate that chimpanzees are more related to humans than they are to gorillas!! (This further supports the theory of Evolution) -
Human Genome is Sequenced (1990-2003)
The Human genome is sequenced, allowing us to get a look of our basic DNA and comparing it to other organisms -
Mary Jane West-Eberhard
Publishes Developmental Plasticity and Evolution, which supports the idea that the environment can cause variation that leads to evolution in a species -
