7. Some gene changes produce LARGE variations. 4 Principals of Natural Selection 1) Overproduction- producing more offspring than can survive 2) Competition- individuals compete for food, nesting sites, territory, & other resources that affect their ability to reproduce 3) Variations- a difference between members of same species that may help it survive and reproduce 8.

Camouflage is the resemblance of one species to another species. Darwin knew that organisms evolved and changed from generation to generation, but did not know how traits were passed on from one generation to another.

Most prokaryotic cells are one-celled, or ___________organisms and are called_______________________, Eukaryotic cells make up plants, animals, fungi and _____________. LESSON 2. Scientific Inquiry Key Concept . His theory was that if an organism continually used a structure to carry out a certain task, the structure used would become physically modified over time to make the task easier. ?
