480-Million-Year-Old Fossil Rewrites Parasite Origins
New fossils push back the timeline of parasitism In a discovery that reshapes our view of early life, researchers have identified fossils from the Fezouata Shale in Morocco that reveal parasitic worms burrowing into mollusc shells about 480 million years ago. This extends the known origin of parasitism by roughly 60 million years, suggesting that…

Intestinal Parasites: Symptoms and Safe Medical Treatment
What are intestinal parasites? Intestinal parasites are organisms that inhabit the digestive tract and feed on nutrients from their host. They include helminths (worms such as roundworms and flatworms) and protozoa (single-celled organisms). While some parasites rely on complex life cycles, others can reproduce inside the human body and trigger symptoms that prompt medical evaluation.…
