2. DAILY DOUBLE Back

3. DAILY DOUBLE Back

4. This type of speciation results if members of the same species are separated and isolated from one another, while this type of speciation occurs if the population comes back together but can’t reproduce with each other Back Allopatric, sympatric

5. These are types of barriers that prevent new species from forming because of potential complications prior to the conception of an embryo Back Pre-zygotic barriers

6. This is the area where new species are able to form Back Hybrid zone

7. This is the process where inherited traits are passed down and result in a lot of phenotypic variation and multiple new species, such as in finches or cichlids Back Adaptive radiation

8. This type of evolution results in similar traits that derived independently in different populations that did not interbreed Back Convergent evolution

9. These were the first living organisms on planet Earth Back prokaryotes

10. This experiment showed how living things could have been formed from nonliving chemicals during the Early Earth conditions Back Miller-Urey

11. This chemical came around after prokaryotes and allowed for many animals to survive Back oxygen

12. These were believed to be responsible for the assembly of RNA monomers Back ribozymes

13. These are known for being able to carry out metabolism and could have served as the first cell membranes Back liposomes

14. This is the naming process that utilizes the genus and species in italics Back Binomial nomenclature

15. This is a method of comparing characteristics within characteristics Back cladistics

16. The presence of jaws was a new development in fish, but was around for a long time before monkeys evolved and had jaws. To fish, jaws would be this type of trait, while for monkeys, jaws would be this type of trait Back Derived trait, primitive trait

17. A group that includes a common ancestor and all of its descendants would be known as this Back monophyletic

18. The simplest explanation is the best describes this philosophy that is applied to the construction of phylogenetic trees Back parsimony

19. prokaryote fossils Back stromatolites

20. new species from two species Back Hybrid species

21. more chromosomes in a species that’s derived from one organism Back autopolyploidy

22. 80% of plant species formed from this type of speciation Back Sympatric

23. Age of the Earth Back 4.6 billion years

24. This is the scientist who is best known for the taxonomy of organisms Back Linneaus

25. Two species that can’t mate because one species doesn’t know how to dance properly during courtship would be separated because of this barrier Back Behavioral isolation

26. This is the theory that eukaryotes gained organelles from prokaryotes Back endosymbiosis

27. This is the name of a table that indicates whether or not organisms have certain traits Back Character table

28. This is the scientist who proposed the idea that populations have limits on their growth Back Malthus

29. Bases created in Nova video Back C, U

30. new mixed species Back Hybrid species

31. Gene studied in Sticklebacks Back Pitx1

32. genes formed through speciation Back Orthologous genes

33. another name for a monophyletic group Back Clade

34. This is the name for the speciation event in which many different animal species evolved Back Cambrian explosion

35. This is the extinction event that allowed for the radiation of mammals Back Cretaceous

36. Prokaryotes are believed to have evolved around this long ago Back 3.5 billion years

37. This is the first organelle that was taken in by the eukaryote during endosymbiosis Back mitochondria

38. These genes are responsible for development and are found in many different organisms Back Hox genes
