Re: An Archaeological Perspective on Parasites

Here's an interesting addendum from the second article in the series:

"Of 16 species that he and other researchers have found, including protozoans, tapeworms, roundworms, flukes, and thorny-headed worms, 11 were almost certainly native parasites that humans encountered for the first time as they intruded on strange new environments in the Americas. The rest were probably old-world species that survived humanity's frozen northern trek. Some, like Ascaris lumbricoides, the large roundworm, evolved eggs that could endure the extreme cold. Others, such as Trichuris trichiura, the human whipworm, eked out an existence in the migrants' heated winter homes." Tweet
