Darwin's Evolution

Artificial selection

is the intentional reproduction of individuals of population that have desirable traits

Testing hypothesis by studying:

comparative embroyology

comparative morphology

molecular evidence DNA

fossils

any evidence of ancient life

Scientific classification of species

Darwin's propositions

If changes occur in the physical enviroment, individuals will be exposed to new circumstances

All species are characterized by variation between individuals

The selective action of the struggle for existence between &within species

Changes which might be effected if there were a similar force acting on nature over millions of years

Aritificial selection has had a marked effect on the formation of domesticated plants & animals

evolution linked to the process of science

Darwin's keywords

The formation of vegetable mould

The descent of man

The origin of species

The Barnacles

The structure & distribution of coral reefs

Mutation

permenant change in genetic material

The Galapagos islands

The type of finches he discovered there which were similar to ones in south America

The voyage of the Beagle

Darwin's misunderstood

Because evolution is not observable or testable, its not science

Evolution &religion are incompatible

Evolution is a ladder of progress

Organisms are always getting better

better is linked to the enviroment

Evolutionary theory is a theory about the origin of life

The fossil record is not complete shows evolutionary theory to be false

Popular misconception of Darwin

Monkeys are the ancestors of men

Newton's theory about the universe which was completed by Darwin

Natural selection

excess of procreation

variation within species

competition between species

Changes in enviroment
