Changes In Morphology That Have Occurred As This Lineage Adapted To An Aquatic Life.

[Name][Instructor][Subject][Date]Changes in Morphology in Whales as They Evolve from sphere MammalsTo Sea MammalsMost people often be wash up mistaken a hunt for a fish because of their skylarks . But whales argon real mammals , which argon animals that have g res publicas that produce milk life military man . It is easy to conclude that whales be more than than closely think to humans than to fishes . This brings confusion to most people for humans are terrestrial animals while whales are aquatic . If it is true that whales are related to humans and to all separate land mammals , how germ they can live on waterJust like humans and other mammals , whales have lungs instead of gills . This centre that they do not actually breathe in while under water . They to a fault have nostrils , called blowholes , which are located on their back (Waggoner . They also have semicircular canals located in their ears . These semicircular canals are responsible for balance . But although whales have massive remains , their semicircular canals are smaller compared to that of other mammals . These organs are also fully developed for aquatic use (National acquirement Foundation . Whales are also warm blooded , which means that they can adapt to changes in temperature of their surrounding . Scientist also provided severalise that the hippos are the close relatives of whales (Braun , 1These characteristics land mammals have in cat valium with whales only brings more confusion . Whales are related to land mammals just still have a fish -life feature . Scientist provided some answers on how these mammals became sea creatures , not by comparison them to present mammals but by comparing them to ancient creatures . numerous paleontologists found fossils of extinct land animals that are even more physically related to whales the only difference is that these animals have limbs . mavin of the most important fossils is the fossil discovered by the root of Phillip D . Gingerich .

What is interesting to this fossil is that it has an mortise-and-tenon joint similar to the articulatio talocruralis of a sheep but with a skull resembling the skull of a modern whale (Braun , 1 . Aside from this , it has been found out that the fossil is more on a terrestrial than aquatic , inferring from the fact that the ankle is better developed for running . The fossil of the Basilosaurus is also a significant disco truly . It is an aquatic animal that have very tiny limbs . These limbs very closely resemble the limbs of the modern whales . many an(prenominal) fossils of prehistoric whales are also found in Pakistan . oneness of which is the Pakicetus , considered to be the earliest whale . Pakicetus also have well(p) developed hind limbs but are aquatic . other fossil found in Pakistan is the Rodhocetus , which is much older that the Pakicetus (WaggonerWhales are really fascinating animals , not only because of their size but also for their true nature and origin . With modern whales have features of land mammals , and their ancestors even having features between a modern whale and land mammals , scientists concluded that whales evolved from other land animals...If you want to get a full essay, order it on our website: Ordercustompaper.com
