in evolution, isolation mechanism is a mechanism that prevents two populations from interbreeding and thus enables the populations to diverge enough to allow separate species to evolve. Isolating mechanisms may also prevent interbreeding between overlapping species.
, Isolation mechanism
Definition:
• Factors that prevent gene exchange
• Agents that hinder interbreeding of the group of individuals
• Isolating mechanisms are particularly important in the biolo
species concept, in which species of sexual organisms are d
by reproductive isolation, i.e. a lack of gene mixture.
• Types: a) Geographical and b) Reproductive isolating
mechanisms

, Geographic Isolating mechanisms
• Occurs when populations cannot mate due to the existence o
physical barriers among them.
• Geographically separated populations aren’t necessarily disti
species
• Leads to the formation of allopatric species: Physical barrier
mountain, lake, fault line formation etc.
