how parasites created sexual reproduction

Hear this out loud
Certain species of parasites can even sexually reproduce with other species, via a process called hybridization.
For example, some schistosome flatworms can infect a wider range of hosts, as a result of a bovine-infecting species mating with a human-infecting species (Huyse et al.
, 2009).

Why do parasites use asexual reproduction?

One theory is that parasites keep asexual organisms from getting too plentiful.
When an asexual creature reproduces, it creates clones – exact genetic copies of itself.
Since each clone has the same genes, each has the same genetic vulnerabilities to parasites.

Why can’t humans reproduce asexually?

Humans cannot reproduce with just one parent; humans can only reproduce sexually.
The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents.
An organism that is born through asexual reproduction only has the DNA from the one parent.
