For questions 32-40, refer to this figure Protostomia Deuterostomia Ma Eon 200 Canbrian Vendian Estimated times of divergence tor lineages of animals, based on the average of several genes. 32. What is the sister-group of the Echindoerms? 33. Name an Animal Phylum that could be used as an out-group in a phylogenetic analysis of the Animals in this figure: 34. Arthropods are closely related to Annelids as/than they are to Echinoderms. a) more b) less c) equally 35. Which two of the lineages presented diverged most recently 36. About how long ago did they (the two most recently diverged lineages) diverge? 37. About how long ago did protostomes and deuterostomes diverge? 38. Based on this figure, you would expect that the amount of sequence divergence between sea urch ins (Echinoderms) an earthworms (Annelids) should be as compared to the sequence divergence between sharks (Gnathostomes) and earth- worms a) much less b) much more c) about the same 39. If a gene evolves faster in Gnathostomes than it does in Molluses, compare the expected divergence between a Mollus and a non-Animal (e.g., a protist or a plant) to that between a Gnathostome and the same non-Animal. a) Molluse to out-group divergence greater b) Molluse to out-group divergence smaller c) hoth about equal 40. Based on this figure, a biologist would be confident regarding the monophyly of the Protostomia, as compared K the monophyly of the Deuterostomia a less b. equally d. can't make such an inference from this figureExplanation / Answer
Answer 15. Option a
Advantageous mutations pass on to further generations.
Answer 16. Option b
Rare variations occurs in the size, as this trait comes under the slow variation.
Answer 17. Option d
This age has been determined by the radiometric dating of fragments from the Canyon Diabloiron meteorite.
Answer 18. option b
It means static balance or equilibrium or stagnation.
Answer 19. Option b
RNA is more primitive than the DNA.
Answer 20. Option c
It is 444mya. It lead to the demisal of the Graptolites.
Answer 21. Option c
Answer 22. Option e
Predation, competition and disease will lead to extinction if the population has low density.
Answer 23. Option b
Cambrian period is known for its predator lifestyles.
Answer 24. Option b
Laurasia in North and Gondwana in the South.
