Natural Selection
Across
- 6. (any disappearance of all members of species.)
- 9. Rock (a type of rock that are formed by the deposition.)
- 13. (produce more offspring than will survive.)
- 15. (the remains of organisms preserved.)
- 16. Selection (species that are best suited to their environment.)
- 17. (the process of species, family, or larger group becoming extinct.)
- 19. Structures (similar structures that related species have inherited from a common ancestor.)
- 20. Dating (is the science of determining the relative order of past events.)
Down
- 1. (the process when species changes overtime.)
- 2. (new species from an existing species.)
- 3. (is an interaction between organisms or species in which both the organisms or species are harmed.)
- 4. (the variety of organisms that inhabit the earth.)
- 5. Islands (Darwin observed finches on this island.)
- 7. of Species (is the abbreviated, more commonly-known title for Charles Darwin's classic, On the Origin of Species by Means of Natural Selection.)
- 8. Darwin (English naturalist, geologist, and biologist.)
- 10. Dating (the process where scientists look at the half-life of chemicals contained in rocks.)
- 11. (any inherited trait that gives an organism an advantage.)
- 12. Breeding (Selective breeding involves selecting parents that have characteristics of interest in the hope that their offspring inherit those desirable characteristics.)
- 14. (a branching diagram showing the cladistic relationship between a number of species.)
- 18. of the Fittest (to be fit you must fit your environment you are well adapted.)
