Question

scientists theorize that all life started with simple prokaryotic organisms. new species continue to evolve from existing species, creating the variety of life we see today. the following diagram shows the basic process.based on this diagram, do you think that organisms of the same order will share a stronger evolutionary relationship than organisms that share only the same phylum?

Answer 1

Organisms of the same order share not only the characteristic of the order they're in but also the characteristics of the phylum they belong to too, because this last category (phylum) is higher in the hierarchy.

Taking this information into account, we can say that organisms of the same order do share a stronger evolutionary relationship than others that only share the same phylum because the first ones share a longer evolutionary story.
