What is a cladogram?

A cladogram is a diagram used in cladistics, which is a method of analyzing biological relationships based on shared, derived traits. It is a branching diagram that shows the evolutionary relationships among a group of organisms based on similarities and differences in their physical or genetic characteristics. The organisms are grouped into clades, which are defined by shared derived characteristics, or synapomorphies. Synapomorphies are traits that have evolved from a common ancestor and are present in all of its descendants.

Hence, the outgroup is a protozoa, and all of the traits that the mackerel has are a jaw, a segmented body, and a multicellular body. Lungs evolved first as frog has lungs and then hair evolved.

The type of ecological succession being described in the illustration is primary succession.

What is primary succession?

It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.

It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.

A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.
