These are the bases that form DNA. A and T match up and C and G match up. if there is a match up like A and C then there is a mutation.
Charles Darwin
Charles Darwin is known for traveling to the Galapagos islands, and learning about adaptations and natural selection, from all the animals there. Darwin also developed a theory of evolution based on this voyage.
Alfred Russel Wallace
Alfred Russel Wallace is one of the lesser known scientists who studied, natural selection and adaptations. unlike Darwin however Alfred Russel Wallace traveled to Brazil to collect specimens, and come up with his own theory.
Tuskless Elephants
This was a modern example of Natural Selection, because elephants were being hunted for their tusks, so they adapted by not growing their tusks.
Gigantopithecus
This giant ape is an example of an animal that failed to adapt to its environment in ancient times. This giant ape ate lots of plants in an area that changed from forest to fields, taking away Gigantopithecus´s food source.
Mutations
A mutation is where an organisms base pairs are paired differently, like T with G, or C with A. Mutations can be helpful, harmful, or have no effect.
Adaptations
An Adaptation is where an animal changes, physical or behavioral features, in order to be more suited in its environment.
Natural Selection
Natural Selection is where traits become less or more popular in a population due to natural selection. for example in a forest with green leaves, all the brown bugs would be less common then the green bugs because, they are easier to see from predators perspective.
Genetics
Genetics is the study of Heredity which is which traits are passed down to you and why. for example in Genetics you could learn about why you have brown eyes when your parents have green eyes.
