Importance of phylogenetic tree
Witryna29 wrz 2010 · Family trees tend to be drawn as if they were hanging upside down, like a cluster of grapes. Phylogenetic trees are depicted somewhat differently. Imagine that you are holding the family tree for the big cats shown in Fig. 2a. Now, flip it sideways (rotate 90° counterclockwise) and you have the image shown in 2b. WitrynaPhylogenetic trees are a fundamental tool to derive useful evidence from the fields of anatomy, paleontology, embryology and molecular genetics. The following are some of the other implications of the evolutionary tree: Used in the search for new species. Used to study evolutionary histories. To study how the species were spread geographically.
