Explanation:
I learned this last year
Explanation:
Broken up land land contributes to a loss of species diversity through geographoc isolation. Geographic 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 in the genome can occur 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.
Such mutations create variations that within a group become dominant, resulting in the creation of different, genetically distinct organisms called species.
