Is the fetus a parasite?

New scientific study proves “fetus as parasite” arguments are false. And if the mother’s health is threatened in some way, the placenta (which is created from cells of the developing child, you’ll recall) will actually take resources from the preborn child to preserve the mother’s health.

Can humans survive without parasites in the womb?

Humans can thrive and survive just fine without any tapeworms, leeches, or parasitic microbes. But the human race would go extinct if we had no fetal humans. While parasites serve no greater good for the human race, children-in-utero are our only hope for survival as a species.

Are there any parasites in humans?
