THEORY OF EVOLUTION

What is Evolution

- Evolution is any change across successive generations in the heritable characteristics of biological populations.

- Evolutionary processes give rise to diversity at every level of biological organization, including species, individual organisms and molecules such as DNA and proteins.

SCIENTISTS WHO CONTRIBUTED TO THE THEORY OF EVOLUTION

Anaximander

Aristotle

Charles Darwin

- Anaximander made the first attempt to offer an explanation of Evolution

- Anaximander put forward the idea that humans had to spend part of this transition inside the mouths of big fish to protect themselves from the Earth's climate until they could come out in open air and lose their scales.

Anaximander

ARISTOTLE Aristotle was a Greek

philosopher Aristotle’s beliefs were

perceived as a “ladder of life” His idea was that all species

could be put in order, from the "lowest" to the "highest,“

starting with worms on the bottom and the almighty man on the top

CHARLES DARWIN

- In a nutshell, when random genetic mutations occur in an organism's genetic code, the beneficial mutations are preserved because they aid survival. Natural Selection

- complex creatures evolve from more simple ancestors naturally over time

- The modern theory of evolution was developed by Charles Darwin, an English naturalist, in the 19th century

NATURAL SELECTION Charles Darwin’s Theory The central concept of

natural selection is the evolutionary fitness of an organism.

“Survival of the Fittest” Natural selection is to

preserve and accumulate minor advantageous genetic mutations.

RELIGION BASED EVOLUTION all the forms of life that

exist on planet earth today have been created by the almighty God.

Creationists believe the Bible’s explanation that God created a number of groups of animals and plants
