Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history. mc022-1.jpg Which can be concluded from a comparison of the two phylogenetic trees? Phylogenetic trees are not subject to change. Classification can change with new discoveries and evidence. Classification does not change with more evidence. Phylogenetic trees are inaccurate.
Answers
A phylogenetic tree indicates evolutionary relationships in organisms.Moreover these are hypotheses not actual facts.This represents species origin from series of common ancestors.From the phylogenetic tree we can understand if two species have common ancestor they are more related and vice versa.This tree can be drawn in many equivalent patterns and its information conveys the same even if it is rotated about it's branch point.
Solution:
Option B is the right answer.
Hence, with the time, classification can change with new discoveries and evidences.
It is quite tough to determine how the particular species evolved and what the changes that occurred through their lineage are. It particularly shows the pattern of descent rather the phenotypic similarity.
