Species, traits

Extinction is caused by a change in a blink environment the members of the species may not have blank that allow them to survive and reproduce in the changed environment

Species,adaptations

Biologist use blank to organize living things into groups so that organisms are easier to study

Classification

Scientist have combined the evidence from blank protein structure fossils early development and body structure to determine the evolutionary relationships among blank

DNA, species

Organisms are placed into blank and kingdoms based on their cell type their ability to make food, and the number of cells in our body's

Domains

Over time, different blank and genetic variation have producedthrough blank selection the variety of blank that exist today

Enviornments, natural,organism
