Mosses or lichens.
Explanation:
Mosses or lichens are the group of species have great impact on the long term dynamics of succession if they develop resistance against fire events because these species can used the ashes of other plants as a nutrients for their growth and development. These group of species spread at a higher rate which covers most of the area of the forest and become a dominant species in the forest. Due to the presence of these species, the organisms who feed on these species comes to these forest and slowly the diversity of the forest is attained.

Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.
