Across
- 3. father of evolution
- 6. leading to the development of a new form, as can be seen through successive generations.
- 7. a metamorphosis during the life cycle of an animal.
- 12. encompasses the growth of both plant and animal embryos.
- 15. a group of individuals of the same species living and interbreeding within a given area.
- 16. the process of surviving
- 18. similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.
- 19. encompasses the growth of both plant and animal embryos.
- 23. all living things have a common
- 24. biological process of development of an organism from the time of birth or hatching into an adult stage by abrupt change in the animal's body such that its mode of nutrition and behaviour, both are changed.
- 25. evidence of evolution
- 26. process by which evolution occurs; natural

- 1. they have the same function but different structure
- 2. population of organisms that can interbreed
- 4. theory that species change over time
- 5. act of improving by expanding or enlarging or refining
- 8. model in which gradual change over a long period of time leads to biological diversity
- 9. is the formation of new and distinct species in the course of evolution.
- 10. refers to the variety of living things
- 11. the transfer of genetic material from one population to another.
- 13. they have the same bones structure but different function
- 14. similarities between species on the molecular level
- 17. when a species dies out, it becomes
- 20. a change in the sequence of an organism's DNA
- 21. humans are regarded as a species
- 22. is the branch of biology that deals with the geographical distribution of plants and animals.
