Fungi were able to colonize the land along with terrestrial plants because
they were decomposers who could release elements tied up in organic matter that would then be recycled by terestrial plants

Cladistics
A theory about speciation proposing that new species continue to change throughout their evolutionary history, diverging more and more from a parent species
Gradualism
A theory about speciation proposing that new species change significantly only when they are branching off from a parent species and then remain unchanged for long periods of time
