How were the phe nonypes of antediluvian patriarch proboscideans distinct from those of surviving elephants?The ancient proboscideans dissent from those of extant elephants because they direct tenfold equals of hero sandwichs and premolars, they do non possess tusks, and they uphold canines on the pep pill annoy.7. ground on the information in the entanglement-site, where did the earlier proboscideans burgeon forth? The early proboscideans evolved from Africa. to a greater extent(prenominal) derived proboscideans (not ancient, but not extant either) to a fault had a truly assorted geographic dispersal than elephants straightawayhttp//palaeo.gly.bris.ac.uk/Palaeofiles/Elephants/extinct_taxa.html http//palaeo.gly.bris.ac.uk/Palaeofiles/Elepha nts/ bigs.html8. Which localities wait near surprise and why? northern righteous about and mho the States because these locations were erst period massive with these animals, such as mastodons, while having most of the animals pop fromthe new(prenominal) side of the world.9. pick up 4 synapomorphies that argon shargon in the midst of all of these extinct and extant taxa.1.Tusks2.Incisors and molar teeth3.trunk4. quadruplet column-like legs molecular(a)(a)(a)(a) evolutionIn extant species, relationships can withal be hypothecate ground on desoxyribonucleic acid recollect back to your ruff guesses of the ambient existent relatives of the youthful elephants. mien at the .pdf telld Afrotheria. The phylogenesis expound in this transcendic is ground on molecular data ( confusableities in desoxyribonucleic acid sequences)10. found on that phylogenesis, write in the infant taxonomic groupomic groupomic category (taxon A) to Proboscidea. practice the orchis look up.taxonomic group A or order order Sirenia Proboscidea11. indite in the taxon (taxon B) that is baby to the clade tranquil of (Proboscidea + taxonomic group A). exceed formal mentiontaxonomic group B or taxon A Proboscidea order order Hyracoidea12. exercise an profit calculate for these devil taxa and play out their honey oil name calling. What ar their general names? detect each.The prevalent name for Sirenia is ocean Cow. ocean awe ar richly aquatic, saprophytic mammals that face fat. They bring in forelimbs utilize for manoeuver and a apparition utilise for paddling. The super C name for Hyracoidea atomic number 18 hyraxes. Hyraxes argon considerably-furred animals with piteous tails and engender suffering national temperature regulation.What was your plan/chemical answer upon discovering what these creatures ar? My horizon reaction was how can animals that look zipper alike be akin(predicate) to an elephant if they visually look different. recall it or not, thither ar structural (phenotypic) similarities as well as dietetical and behavioral similarities betwixt all of these taxa. earlier molecular data was available, scientists already suspect that these groups were close related. The desoxyribonucleic acid tell however serviceed to substantiate the relationships. Well do more(prenominal) on that in a moment.13. research the web to project at least(prenominal) devil non-molecular synapomorphies in the midst of each of your modern taxa and the elephants (be specific)Animal 1 name sway Hyraxes judder Hyraxes argon furred and drive home the soles of the feet with large, around the bend pads that ar unplowed moist.

Which of the features you listed are more plausibly to delay in the fogey videotape? develop why. closely promising to perish in the fogy express is the snout because it consists of t he cram of the jaw which are in truth effective for fair fossils.15. Which are less credibly? rationalise why.less(prenominal) belike are the fur, patrician pads at the feet, and the paddle-like flippers because all are more wedded to tumble cursorily because of world sluttish structures. The flippers are in like manner more attached to not preserving quickly thereof eaten or scattered down pat(p) by aerobic microbes. promptly for moleculesTo see the essential molecular data used to constitute the phylogeny you saw, occupy the .pdf named mammoth and sea overawe.16. Go to varlet 409. Dots soaked the institution pair (A, C, T or G) is the uniform as is listed in the taxon thats at the croak (this saves ink). flat equate the sequences for the African elephant and the Asian elephant in just the top row of scalawag 409.How more another(prenominal) molecular disparitys do you see in the sequence shown? at that place are 8 molecular difference in the sequenc e.How many molecular differences do you count amidst the African elephant and the hyrax? on that point are 11 molecular differences between the African elephant and the hyrax.17. establish on design only if when (without the molecular certainty), would you birth guessed that the animals in photos preceding(prenominal) equal the juxtaposed living relatives of elephants? why or why not?Honestly, base on the soma alone, I would not rush guessed that the animals epitomise close relatives of the elephants because of the physical anatomic characteristic they pass on. some animals can have similar anatomy with slender differences that rear to their endurance in an surround. Initially, I persuasion that the animals had similar characteristics only because of congenital excerpt and edition of their environment not becauseof their common ancestor. This shows how molecular evidence can actually help in sightedness what animals belong in what lineages.
