- 8. – When two species that have different ancestors develop similar traits
- 10. – The divergence of one species into many over time.
- 11. – When a trait from an ancestor reoccurs.
- 12. – A structure that has no function that is a remnant of a past ancestor
- 14. -reads mRNA and synthesizes polypeptides
- 15. - What our genes are made of
- 17. The diverging of traits into different species from a common ancestor.
- 18. – Looking at the embryo of a species to determine its common ancestors.
- 19. – Observed that there were factors that controlled populations. Precursor to Darwin’s’ survival of the fittest.
- 20. – All organism in a specific group.
- 24. - single stranded & is created in the nucleus by reading DNA
- 25. - the representation of traits
- 26. – The process through which organisms that have the best fitness are able to change the gene frequency over time to evolve. Includes Survival of the fittest.
- 30. – The effect where random chance affects the gene frequency of a population.
- 31. - When a trait is overshadowed by another
- 32. – The relative proportions of genetic variations within a population.
- 33. - when mRNA is read by the ribosome to create amino acid chains.
- 34. -When two organisms with different ancestors develop similar traits.

- 1. -Father of evolution. Determined the evolution of organisms through the process of evolution through the theory of natural selection.
- 2. – A structure originating from a past ancestor but with different uses.
- 3. - When traits blend together
- 4. -When both traits appear
- 5. – The process in which humans change the gene frequency of a population.
- 6. – Believed that organism evolved by the process of improving themselves.
- 7. acids - are attached to tRNA, form a chain that it turned into a protien
- 9. - where DNA is transcribed into mRNA
- 13. - the genes that codes of a trait
- 16. -the changes in traits that affect an organism survivability. This can be behavioural changes.
- 21. – The collection of all the genetic population of a species.
- 22. -The ability for an organism to survive and pass on its traits to its offspring
- 23. -Determined that the Earth was old. A father of geology
- 27. - When there are two different alleles
- 28. -When organisms traits closely match their local environment.
- 29. - the parts of our genes that have for traits
