1. Evolution

2. Evolution
Evolution is defined as the change in genetic characteristics of populations of species over generations; typically thousands of generations are needed before characteristics are fully changed.

4. Evolution
The genetic changes are due to mixing of gene pools within species due to sexual reproduction as well as genetic mutations that are constantly occurring and being edited by nature. i.e. Natural Selection.

5. Natural Selection - Darwinism
Proposed by the English naturalist, Charles Darwin in 1859, natural selection is the way nature edits which genetic traits are favorable and will survive from generation to generation and which will die off. “Only the strong survive!”The traits that increase an organism’s chance of survival is an adaptation.

8. Adaptations
A Kiwi bird has adapted to reaching ants under ground with its elongated mouth and tongue.

9. Coevolution
Organisms evolve adaptations to other organisms and to their physical environment. The process of two species evolving in response to long-term interactions with each other is called coevolution.

11. Symbiosis
 Any types of persistent biological interactions i.e. mutualistic where both organisms benefit, commensalistic where one organism benefits without affecting the other, or parasitic where one benefits at the other organism’s expense.

12. In a symbiotic mutualistic relationship, the clownfish feeds on small invertebrates that otherwise have potential to harm the sea anemone, and the fecal matter from the clownfish provides nutrients to the sea anemone. The clownfish is additionally protected from predators by the anemone's stinging cells, to which the clownfish is immune.
