A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.
(Loxodonta and Mammuthus can also be reversed)
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
Sequence differences in genes or genomes are used to determine organisms that are most related to each other based on evolution.
Sequence differences are differences which exists in the entire genome or a gene which code for proteis s whivh are related on function or structure in two organisms.
For proteins performing similar functions, organisms which have the least sequence differences are usually the most related organisms in an evolutionary sense whereas, organisms with the most sequence differences are the least related.
Therefore, sequence differences in genes are used to determine organisms that are most related to each other based on evolution.
