Textbook definition:evolution toward similar characteristics in unrelated species, resulting from adaptations to similar enviornmental conditions.My Definition: Species that aren't closeley related evolve similar characteristics which results them to having or evolving in the same enviornmental conditions.

Textbook Definition:principle that states that the changes in landforms results from slow changes over a long period of time.My Definition: Changes in enviornment will cause species to evolve slowly over long periods of time.

Textbook definition: theory that states that speciation occurs suddenly and rapidly followed by long periods of little evolutionary changes.My Definition: Species evovles fast in a short period of time, but then in a long period of time, the species had rarely evolved. i t doen't really evovle as much in a long period of time.

Textbook definition:evolution of one or more closely related species into different species; resulting from adaptations to different enviornmental conditions.My Definition: Species become different over time and resulting them to become extinct or the population might grow.

Textbook definition:process in which two or more species evovle in response to changes to each other.My Definition: when two species that closely in teract with each other and one of the species adapts something from the other . which causes them to evolve.

In this picture, this would be co-evolution, because the bee is interacting with the flower. Also i believe that this is an example, because the bee has adapted the yellow color stripes, because of the pollen that the flower gives off. the bee has adapted to the pollen so therefore it got a yellow strip.

In this picture, as you can see, areexamples of convergent evolution, because the thylacine, and the dingo have similar charcteristics even though they aren't related, but they can adapt or evolve in either of their enviornments.

This picture is an example of divergent-evolution, because you have this species that has been evolving over time, adapting to different enviornmental conditions creating new species each time.

In this picture, the land-form, or environement caused slow changesin evolution resulting inevolution to occur slowerand the species of the giraffe doesn't exist untilyears later.

In this picture, species evolves fast in a short period of time, but in a long period of time, it takes longer for the species to evolve.
