A universal phylogenetic tree is a term coined for the evolutionary tree of life in which we can notably recognize from the name of the representation that it is about the relationship between evolution and various species of animals primarily classified and revolutionized in a tree like branching representational diagram. The data displayed on the tree are classified and drawn in accordance to similarities and differences in both physical and genetic materials. Species placed in the tip of the tree are the modern animals that are around today. The tree is usually drawn from a mutual ancestor specie and branched out into different species that is caused due to gene mutations and environmental factors thus animals branched out from a common ancestor would have similar traits between them called homology which may be in either gene sequence or structure. Diagram 1 is a phylogenetic tree.…show more content…
A few species possibly had advanced a considerable measure yet some perhaps didn't developed much. The sample of species that had advanced essentially is giraffe. Those days, giraffes have short neck therefore their ancestors had short neck. Apart from giraffe, there are other creature likewise eat the lower vegetation. As the time went on, the lower vegetation decreased. Since lack of food, creatures need to compete among themselves to survive, so giraffe began to acquire nourishment from higher vegetation. This prompted the development of giraffe where their neck becomes longer and more over a long of time which helped giraffe to reach the higher vegetation easily and survive. Because of the environmental factor, extraordinary characteristic which doesn't exist in predecessor of giraffe had created and has advantage that carry on to their offspring subsequently a present day giraffe are showed
