Who was Charles Darwin?

Selection?
Darwin served as naturalist aboard the H.M.S. Beagle which

was a ship that was on a British science expedition traveling around the world.
In South America Darwin found fossils of extinct animals that were similar to modern species.
On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America.
The expedition visited places around the world, and Darwin studied plants and animals everywhere he went, collecting specimens for further study.
Darwin studied the specimens he collected on his journey on the H.M.S. Beagle for many years and reviewed the journals of observations from his trip to develop his “Theory of Natural Selection”.

adapted for survival are the ones that are chosen

for reproduction. Only those organisms that reproduce pass on their traits.

adapted to their environment are the ones that survive

and reproduce.

More young are produced than can survive.

Organisms compete for needed resources.

Variations are passed from parents to offspring.

Only those organisms that reproduce pass traits to the next generation.

Major Points of Natural Selection

species survive.
One type of adaptation organisms have are structural

adaptations. A structural adaptation is a body structure that enables the animal to perform specific functions.
Camouflage is a structural adaptation that enables an animal to blend with its surroundings.
