Not guarantee, but it is rather helpful. It is not too likely that two population split by a solid geographic barrier would not begin to speciate. To not speciate they would have to not have any beneficial mutations over time that would carry their gene pools apart. Then there is the possibility of founder effect by having the frequency of alleles vary between the two populations in a random manner. So, not guarantees, but even modern ring species vary greatly enough that at the ends of the ring they are different species. ( Google ring species )

Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
Because the pollen from one specie will not fertilize a seed from another specie.
Massachusetts taxes are paid in specie for two different reasons. One reason was because specie was rare and for two specie was worth more.
An exotic specie. An alien specie. A non-native specie. All are acceptable.
Insects actually have more than one specie. Insects are a life group. For example, a specie would be predator insects, which is one specie. Insects actually have more than one specie.

Antigen present in a specie of individual and that can provoke an immune response in another individual of the same specie
Specie is money to pay taxes used in the colonial time during theoaid 17 and 18 hundreds. Usually colonists paid their taxes off in gold and silver. This is considered specie.
