He loved science and had the brains to come up with natural selection. He had the most information on natural selection and evolution, he also had the resources to get more information on natural selection and evolution.

He grew up with the science view on things. Made observations and studied plants as a boy. He studied natural selection and evolution.

He is given credit for Proving that natural selection and evolution effected the population of Plants and animals.

On his voyage Darwin found many species of insects. He filled his notebook with observations about different habitats and characteristics of the species he found.

1. flightless, ground dwelling birds called rheas living in the grassland of south America, and they only lived in south America.

2. A large flight less bird, the emu.

3. Rabbits and other species living in European grass land were were missing from the grass lands of south America.

Darwin also collected fossils. He found fossils of giant armored animal called the glyptodant, this looks similar to the armored animal we call the armadillo.

Common ancestors are species that still live today and species that are extincted. Humans are common ancestors, so are cats, dogs, panthers, tigers, birds, and fish.

over time species had been growing and reproducing creating many different DNA structures of all shapes sizes, and characterization.

structures that are shared by related species and that have been inherited from a common ancestor are called homologous structures.

Body parts that share common function, but not structures, are called analogous structures.

vestigial structures are inherited from ancestors but have lost much or all of their function due to different selection pressures acting on the descendant.

Now we have all these factories and tree mills that many species are now home less because the trees are being cut down. Those species are decreasing in size because they cant catch their food with out trees. Other species are becoming bigger from the amount of food they can find with out trees.

If an area begins to have less medium sized seeds and more small and large seeds. the birds with small and large beaks will have high fitness, this is known as disruptive selection.

Babies that are lower than average weight are more likely to not survive. Babies that are larger are more likely to be born more difficult. so medium babies are gonna be the best, this is called stabilizing selection.

The range of prototypes shifts because some individuals are more successful.

Any heritable characterization that increases an organisms ability to survive and reproduce in its environment is called an adaption.

Fitness describes how well an organism can survive and reproduce in its environment.

Survival of the fittest means if a tiger is trying to catch a cheetah the cheetah will out run the tiger.

Natural selection is the process by which organisms with variations most suited to their environment and leave more offspring.

Fossils tell that there was some type of dinosaurs and that there was plants.

Differences in fossils and the living thing show evolution.

The isabela tortoise has a dome shaped shell and short neck.

the hood tortoise has a curved and open shell around their long neck and legs.

This is a giant tortoise, bigger than the other two. Its neck is not surrounded by the shell.
