Question

On a branching chart showing the evolution of species over time what does each branch represent

Answer 1

In evolution, there are different types of evolution. There is micro evolution and macro evolution. Macro-evolution results in a brand new species. Sometimes, species get separated and evolve in different ways. Sometimes, through macro-evolution 1 of those groups of the same species, become a completely different species. I think that is what is happening here. 

Answer 2

The correct answer would be species.

Phylogenetic tree refers to the diagrammatic representation of evolutionary relationships among different organisms.

The branching pattern indicates how species evolved from a sequence of common ancestors.

The tip of each line or branch indicates a separate species.

Each internode or branching point represents a divergent event in which a single group splits into two descendant groups.
