Darwin's evolution

The Galapagos Islands played a crucial role in Charles Darwin's development of the theory of evolution, particularly through his observations of finches, whose beak sizes varied significantly from other species.

Darwin's evolution

Darwin's theories of evolution misconceptions

Humans are originally monkeys
fossil record isn't complete so the evolutionary theory is false
Because evolution is not observed and testible,so it is not a science
Artificial selecetion
Genetic mutations"fruits"
the fossil record
Evolution theory is a theory about the origin of life
Darwin's focus was on earth's changes on the earth
Evolution is a ladder of progress

Evolution and religion contadict?!

Gensis book's formation of the world can agree with science
time-tested evolution doesn't refute the presence of god

The Golapogos islands' role

the Finches discovery
differ from other species in the Beak size
similar to others in South America
alot of observations were done
not inhabited by humans
Isolated islands from the main land

Darwin's propositions

All human beings share a common ancestor
monkeys,and other apes are our closest relatives
Artificial selection"selective breeding"
desirable traits

increase the size like great dane

the process of evolution takes a very long time
not necessarily the change is a bonus/good
the selective action happen when species struggle to survive(natural selection)
the fittest or well adjusted biologically

pass the favorable traits to offspring

genetic mutation/variation
competion within individual to survive
changes in the environment
The change in the physical environment caused individuals to new circumstances
new species from the natural selection

Darwin's book"the origins of species"1859

Evidence of evolution
the fossil records show different living populations over time

the existance of mammals

particular species aren't very identical but can differ
the rise of new species need "Geographical isolation"
differences like some run faster,various colors
differences are inherted and passed to offspring
Darwin's theories of evolution
based on observation
