Question

Look at the phylogenetic tree. Do robber crabs have more in common with humans or with sponges? What conclusion can you reach about their evolution?

Answer 1

Answer:

Robber crabs have more in common with humans than sponges.

Explanation:

Robber crabs have more in common with humans than sponges because sponges don't have tissues. Crabs and humans have specialised tissue.

Answer 2

Answer:

Hope this helps! From Plato

Explanation:

Robber crabs have more in common with humans, which are vertebrates. Sponges are simple organisms that don’t have tissues. Crabs and humans have specialized cells and tissues, bilateral symmetry, and a coelom. According to the phylogenetic tree, vertebrates and arthropods have more nodes, or common ancestors, than crabs have with sponges.
