Northwestern University Zhang Zhifei and colleagues analyzed the fossil population of Neobolus Wulongqingensis, a Cambranian wrist-footed animal found in Yunnan, and found that ancient wrist-footed animals were parasites of a creature that could turn the food of wrist-footed animals into self-feeding. The discovery marks the oldest known parasitic relationship in the fossil record. The results were published June 2 in Nature -Newsletter.
is a small shelled marine animal, shaped like a biscele, with about 450 species present, but fossil records show that there are more than 12,000 species.
animals needed to fight parasites shortly after the Cammatic outbreak (about 541 million years ago). This time, Zhang Zhifei and others analyzed the fossil population of the new round shells found in Yunnan, measuring the year of about 512 million years ago. They found that many of the new round shells of the oolongyu shell covered with a tube living organism, while the new round shell covered with the tube living creatures is significantly smaller, and these tulle structures are consistent with the direction of the carpal foot animal's own feeding water flow. Therefore, the authors argue that this tube creature weakens the host's health by stealing the host's food (stealing parasitic phenomena). (Source: Feng Lifei, China Science Journal)
