5. It is assumed that early human ancestors
generally had parasites, but until recently there
was no evidence to support this claim. Generally,
the discovery of parasites in ancient humans
relies on the study of feces and other fossilized
material. The earliest known parasite in a human
was eggs of the lung fluke found in fossilized
feces in northern Chile and is estimated to be from
around 5900BC. There are also claims of
hookworm eggs from around 5000BC in Brazil
and large roundworm eggs from around 2330BC
in Peru. Tapeworm eggs have also been found
present in Egyptian mummies dating from around
2000BC, 1250BC, and 1000BC along with a well
preserved and calcified female worm inside of a
mummy.
9. The Protozoa parasite are single-celled organisms. They can attack
any single cell. They also duplicate themselves in your body the
same way virus or bacteria do. Theses parasites can be found in the
blood and the nervous system. A well known disease cause by a
blood parasite is malaria. Tuberculosis is also caused by a blood
parasite that lives in white blood cells. The different species of
Protozoa can enter you body in many different ways. They can be
transmitted by insects or through water. There are also many
Protozoa's that can enter your body by undercooked meat.

your body as eggs if you eat infected or undercooked
meat. Roundworms can also be ingested by drinking
infected water. They hatch and live in your intestines
stealing the food and nutrients. Roundworms can be
white or pink. The most common of Roundworms
Pinworms, Hookworms, and Whipworms.
11. The Flukes are a type of parasitic worm that are oval shaped
but flat. Flukes can be found various organs such as liver or
organs and sometimes in the blood. The blood Flukes travel
through different organs in the body and are especially
dangerous because they can infect the brain and spinal cord.
12. This category of parasites
include those that are
insects. The common
insects are fleas, lice, ticks,
and mites. These parasites
