Pierre Louis Maupertuis theory
Maupertuis espoused a theory of pangenesis, postulating particles from both mother and father as responsible for the characters of the child.[5] Bowler credits him with studies on heredity, with the natural origin of human races, and with the idea that forms of life may have changed with time.[6] -

Alfred Russel Wallace
Alfred Russel Wallace was a British naturalist, explorer, geographer, anthropologist and biologist. He is best known for independently proposing a theory of evolution due to natural selection. -
Voyage of the Beagle
On 27 December 1831, the voyage lasted almost five years and, as FitzRoy had intended, Darwin spent most of that time on land investigating geology and making natural history collections -
darwin had be working on his theory
Darwin had been working on his theory since 1837, soon after his epic voyage on the HMS Beagle. The hypermethodical naturalist wanted not only to classify the prodigious variation he had observed, but also to explain how it came to be. -
published a new evolutionary theory
Charles Darwin and Alfred Russel Wallace published a new evolutionary theory that was explained in detail in Darwin's On the Origin of Species -
tree of life
Unlike Lamarck, Darwin proposed common descent and a branching tree of life, meaning that two very different species could share a common ancestor. The theory was based on the idea of natural selection -

Alexander Oparin
In the 1930's a russian scientist, Alexander oparin hypothesized that life began in the oceans on early earth,He suggested that first, simple organic molecules containing carbon formed. Energy from the sun, lightning, and earth's heat triggered chemical reactions to produce small organic molecules from substances present in the atmosphere. -
population genetics became integrated
1930s and 1940s, population genetics became integrated with other biological fields, resulting in a widely applicable theory of evolution that encompassed much of biology—the modern evolutionary synthesis. -
