Evolution

Charles Darwin

“Grandfather of Evolution”Theory of Natural Selection “Origin of Species”

Jean-Baptiste Lamarck

First person to attempt an explanation of Evolution

First to put the idea of Evolution into a Scientific Theory

Father of “Lamarckism”Lamarckism is the idea that an organism can

pass on characteristics that it acquired during its lifetime to its offspring 

Lamarck proposed the inheritance of acquired traits, which was later proved to be wrong

Charles Lyell

“Principals of Geology”Lyell argued that the formation of Earth's

crust took place through countless small changes occurring over vast periods of time

Gregor Mendel

Created the Theory of Inheritance and Heredity

“Mendel’s Genetics”

Alfred Russel Wallace

Contributed to the Theory of Natural Selection with Charles Darwin

 Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridization.

Homologous Structures and Vestigial Organs

Homologous Structures – Similar Body parts of two organisms that share a common ancestor

Vestigial Organs – an organ that no longer has a useful function in an organism (Tail in humans)

Development in Brain Size

Humans have Protein Domain in the genome, and more than 270 copies of it, more than any other species

Protein Domain at issue (Scientifically) is called DUF1220

The Closer a species is to a human, the more Protein Domain they have, for example Chimps

Development of Language

Humans are the only Species that has evolved with an advanced system of communication between individuals, while other species communicate through calls, gestures of songs, we humans have language

First language appeared between 30,000 and 100,000 ago in Homo Sapiens

Coevolution

 Coevolution is the change of a biological object triggered by the change of a related object

An Example :

Yucca moths and yucca plantsYucca flowers are a certain shape so only that tiny moth can pollinate them. The moths lay their eggs in the yucca flowers and the larvae (caterpillars) live in the developing ovary and eat yucca seeds.
