Question

branches

1. each branching point represents a point in evolutionary history where an ancestral evolutionary lineage gave rise to a new lineage. the most recent common ancestor shared by all lineages in this cladogram is represented by the number 1

the most recent common ancestor shared only by gymnosperms and angiosperms is represented by type here

Explanation:

Step1: Identify the key - concept

In a cladogram, the branching point represents the most recent common ancestor.

Step2: Locate the relevant branches

We need to find the branching point for gymnosperms and angiosperms.

Step3: Determine the number

By observing the cladogram, the branching point for gymnosperms and angiosperms is represented by the number 5.

Answer:

5
