Evolution Of A Salamander

According to Charles Darwin , organisms hold back a cancel tendency to arrogate favor fitted traits of past generations into future generations as well as discard traits that are non so useful or go through become obsolete in their usefulness (Gould , 2002 . This is what is in a flash knows as the hypothesis of natural selectionThe poker game is an amphibious puppet with 500 species . They are normally characterized as having slender bodies with farseeing tails and short legs . Most species of fire hooks have four legs (Farrand , 2003 The expulsion to this is the aquatic salamander belonging to hoagie Sirenidae which scarce has two very miserable forelimbs and lose whatsoever hind(prenominal)er(prenominal) limbs (Farrand , 2003 . These creatures are often referred to as sirens (Farrand , 2003In to be able to pardo n the evolution of these aquatic salamanders through the use of Darwin s theory of natural selection , it is important to take into consideration any potential uniqueness in the habitat , nourishment line , and general way of life of this aquatic salamander that is not give in in the cases of its relatives . For example , the aquatic salamander s diet includes small fish and shrimps (Farrand 2003 . These prey would not be so slowly caught by creatures that have much cislunar characteristics such as better developed fore and hind legs .

It can be hypothesized that in the evolution of aquatic salamanders , more a bundant forage source in their natural habi! tat were free-swimming aquatic creatures . Thus over their evolutionary old age , the predecessors of the siren toss their hind legs in favor of fleet and better mobility in the water given its more gay physical expression with the absence of its legs . Natural selection do this happen so that the aquatic salamander can have better approach shot to the more abundant food source available to themReferenceFarrand , M (2003 .
