what causes a branch in a cladogram
Answers
A new branch in a cladogram is given when a new trait arises that sets apart those organisms from the rest of the clade. A clade is a group of organisms that share a common ancestor. Although the organisms within a clade and their shared ancestor will have similar characteristics each branch will have a unique character or trait.
A branch in a cladogram arises when new traits are recognised in some organisms.
EXPLANATION:
These traits set apart the organism from the others in a clade. A clade is a 'group of organisms' that come from the same ancestors.
A 'cladogram' is basically a 'diagram' that shows different organisms and the relationships that exist between the organisms. Lines are used in cladograms to represent the different clades or branches. When a new branch arises in a cladogram, a new line is drawn to show the organisms having common and unique traits.
