Hydrogen sulfide gas
Volcanic gases are gases from volcanoes. These are gases trapped in the spaces between volcanic rocks. The sources of this gases are the recycled constituents of the earth mantle, assimilated constituent of earth crust and groundwater, earth atmosphere. The principal component of volcanic gases are water vapor, carbon dioxide, sulfur dioxide , hydrogen sulfide. Gases varies depending on the volcano, water vapor is the most common among the gases.

Answer;
Gene flow
Gene flow is the most important factor that holds a gene pool of a species together and prevents speciation.
Explanation;
-Evolution may occur as a result of genes being transferred from one population to another. This gene flow occurs when there is migration. The loss or addition of people can easily change gene pool frequencies even if there are no other evolutionary mechanisms operating.
-Gene flow may also occur without migration, for instance, when people travel to another area and successfully mate with people in the population there, a transfer of genes occurs between the populations even though the traveler returns home.
-Additionally, gene flow may flow between species. A good example is when segments of DNA are transferred from one species to another by viruses as they invade the cells of animals or plants.
