Explanation:

2. distribution and abundance of organisms

3. speciation of plants

4. Antarctic convergence

Geographical isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.

Further Explanation:

Spontaneous modifications within the genome may arise during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.

These mutations form variants which, within a population, become stable, resulting in the formation of separate, genetically distinct populations called species. Apart from allopatric speciation, new species arise through several other evolutionary mechanisms such as:

  • peripatric speciation— like allopatric speciation, however, one group is much smaller, making the unique characteristics more notable, or distinct
  • parapatric speciation— sub-populations in a large geographic region develop reproductive isolation by mating with those nearby, but continue to undergo reproductive isolation;
  • sympatric speciation-absence of physical barriers that impede the passage of genes; reproductive segregation by many variants of the same genes called polymorphisms
