Theroy of Evolution
By: Beth, Melissa, Jun and Cullen
1. "Their studies reveal evidence of degrees of relatedness between different species. This evidence implies that some species share a more recent common ancestor..."
2. "Additional evidence that these organisms descended from a common ancestor"
Vestigial organs are structures when there are some organisms that have structures but aren't useful but useful in other species. How there are eyes on snakes but some snakes are blind. It's significant because their ancestors were the same but branched off to form new species.
"Nicholas stenom noted the similarity between shark teeth and tongue stones."
This shows that fossils are evidence the theory of evolution is true
There are two ways that help show changes in evolution over time, natural selection and changes in species
Biogeography shows how species have evolved over time and change in height weight etc.... This can help us discover how long evolution was ago and the affects it has on us so we can predict the future.
Examples of this are weaker animals are becoming extinct do to the process of evolution
Another example is scientist have discover animals and humans adapted to different environments
