Human migration and global trade are two factors that have altered geographic distribution of parasites. one result of this phenomenon is that humans are introduced to new infections more often, and they can be co-infected by several parasites from different species or lineages. these co-infections can result in matings between individual parasites of the different species and lineages. what biological diversity concept does this phenomenon provide evidence for? a) hybridization of species, specifically parasites
b) ecological niches
c) reproductive barriers
d) geological barriers

a) hybridization of species, specifically parasites

Explanation:

Hybrid speciation is a kind of speciation that is caused by reproductive isolation from the parent species. In this the hybridization occurs between the two different species which leads to the formation of new species.

The hybrid formed because of the hybridization of the species that belong to the same genus called as interspecific hybrids and those formed between different sub-species are called as intra-specific hybrids.

Here, in the given situation, the hybridization of the different species of parasites due to geographical distribution of parasite due to global trade has resulted which is responsible for co-infections.
