  1. 8. – When two species that have different ancestors develop similar traits
  2. 10. – The divergence of one species into many over time.
  3. 11. – When a trait from an ancestor reoccurs.
  4. 12. – A structure that has no function that is a remnant of a past ancestor
  5. 14. -reads mRNA and synthesizes polypeptides
  6. 15. - What our genes are made of
  7. 17. The diverging of traits into different species from a common ancestor.
  8. 18. – Looking at the embryo of a species to determine its common ancestors.
  9. 19. – Observed that there were factors that controlled populations. Precursor to Darwin’s’ survival of the fittest.
  10. 20. – All organism in a specific group.
  11. 24. - single stranded & is created in the nucleus by reading DNA
  12. 25. - the representation of traits
  13. 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.
  14. 30. – The effect where random chance affects the gene frequency of a population.
  15. 31. - When a trait is overshadowed by another
  16. 32. – The relative proportions of genetic variations within a population.
  17. 33. - when mRNA is read by the ribosome to create amino acid chains.
  18. 34. -When two organisms with different ancestors develop similar traits.

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