A __ shows how groups share common features. Cladogram Phylogenetic tree VIDA chart Differential survival

## Step 1
The question is asking for the term that describes a diagram that shows how groups share common features. This is a concept in biology, specifically in the field of taxonomy, which is the classification of organisms.

## Step 2
A cladogram is a diagram used in cladistics which shows relations among organisms. A cladogram is not a tree, but a diagram that shows the evolutionary relationships among various species that are based on their shared derived characteristics.

## Step 3
The other options, Phylogenetic tree, VIDA chart, and Differential survival, do not fit the description given in the question. A Phylogenetic tree is a diagram that represents the evolutionary relationships among various species, but it is not specifically about shared common features. A VIDA chart is not a recognized term in biology. Differential survival is a concept in evolutionary biology, but it does not represent a diagram.
