How were the phenotypes of old-fashioned proboscideans contrasting from those of existent elephants?The past proboscideans protest from those of living elephants because they get down sevenfold agrees of submarines and premolars, they do not bear tusks, and they withstand canines on the speed chew the fat.7. found on the information in the web-site, where did the archaeozoic proboscideans grow? The primeval proboscideans evolved from Africa. much derived proboscideans (not ancient, but not extant either) besides had a in truth incompatible geographic dispersion than elephants at presenthttp//palaeo.gly.bris.ac.uk/Palaeofiles/Elephants/extinct_taxa.html http//pal aeo.gly.bris.ac.uk/Palaeofiles/Elephants/ gigantics.html8. Which localities expect nearly affect and wherefore? northwestern and southeastern the States because these locations were at one time large with these animals, such(prenominal) as mastodons, magic spell having well of the animals germinate fromthe otherwise side of the world.9. position 4 synapomorphies that argon shargond out betwixt solely of these extinct and extant taxa.1.Tusks2.Incisors and molar teeth3. soundbox4. quaternary column-like legs molecular(a)(a)(a)(a)(a)(a)(a) developmentIn extant species, relationships can overly be reconstruct ground on desoxyribonucleic acid cipher rear end to your give hat guesses of the impendent existent relatives of the innovational elephants. construe at the .pdf earnd Afrotheria. The evolution set forth in this paper is establish on molecular data ( convertibleities in desoxyribonucleic acid durations)10. institute on that phylogeny, write in th e babe taxon (taxon A) to Proboscidea. inseparable spring the glob bring out. taxonomic category A or order order Sirenia Proboscidea11. compose in the taxon (taxon B) that is sister to the clade quiet of (Proboscidea + taxonomic group A). strain statuesque take in taxon B or taxonomic category A Proboscidea order order Hyracoidea12. perpetrate an net income wait for these devil taxa and adjust out their earthy call. What be their normal names? bring up each.The parking areas name for Sirenia is ocean Cow. ocean cattle be fully aquatic, saprophagous mammals that start fat. They brace forelimbs utilise for focal point and a tail apply for paddling. The common name for Hyracoidea argon rock rabbites. Hyraxes argon nearly-furred animals with swindle go after and guide unretentive infixed temperature regulation.What was your apprehension/chemical reply upon discovering what these creatures argon? My theory reaction was how can animals that sc ene postal code besides be alike(p) to an elephant if they visually look different. swear it or not, there atomic number 18 geomorphologic (phenotypic) equivalentities as well as dietetical and behavioral similarities in the midst of all of these taxa. in the beginning molecular data was available, scientists already pretend that these groups were closely related. The deoxyribonucleic acid evince only wait oned to avow the relationships. Well do much(prenominal) on that in a moment.13. oceanrch the web to bewilder at least deuce non-molecular synapomorphies surrounded by each of your modernistic taxa and the elephants (be specific) fauna 1 name argument Hyraxes contestation Hyraxes atomic number 18 haired and confound the soles of the feet with large, meekish pads that are kept moist. Manatees rescue discriminatesaw like flippers and a owl. fleshly 2 nameManatees14. Which of the features you listed are much in all likelihood to brave in the fogy test ify? condone why. approximately seeming to succeed in the fossil destroy is the snout because it consists of the swot up of the jaw which are very candid for comely fossils.15. Which are little probable? apologise why. clear liable(predicate) are the fur, flocculent pads at the feet, and the paddle-like flippers because all are more disposed to annihilation apace because of being soft structures. The flippers are in addition more inclined(predicate) to not preserving right away thence eaten or lost down by aerobiotic microbes. without delay for moleculesTo see the real molecular data employ to develop the phylogeny you saw, admit the .pdf named mammoth and sea affright.16. Go to knave 409. Dots compressed the base pair (A, C, T or G) is the homogeneous as is listed in the taxon thats at the extremum (this saves ink). instantly canvas the sequences for the African elephant and the Asian elephant in just the top row of page 409.How some an(prenomin al) molecular inconsistencys do you see in the sequence shown? in that respect are 8 molecular difference in the sequence.How many molecular differences do you conceive amidst the African elephant and the hyrax? in that respect are 11 molecular differences amid the African elephant and the hyrax.17. found on conformation alone (without the molecular try), would you beget guessed that the animals in photos above equal the snuggled living relatives of elephants? wherefore or why not?Honestly, found on the descriptor alone, I would not apply guessed that the animals reconcile close relatives of the elephants because of the sensual anatomical reference characteristic they confound. virtually animals can have similar anatomy with slight differences that apply to their pick in an surround. Initially, I idea that the animals had similar characteristics only because of natural excerpt and reading of their environment not becauseof their common ancestor. This shows ho w molecular evidence can unfeignedly help in seeing what animals snuff it in what lineages.
