Extinct because ... sex organs are too big

American paleontologists have found the cause of extinction of some ancient species, which are "overly" sexual organs and the responsibility of maintaining the race.

A study published in Nature reveals the curtain of the disappearance of some ancient organisms. They analyzed chronological fossils of nearly 500 million years of the ancient ostracods and found it to have a rather large sexual organ compared to the body and a " heavy " responsibility to increase the population of the species. .

Ostracods have the outer shell of space mainly used to contain . genital organs. The large size machine helps it produce more sperm and sperm length is up to 20% -30% of the total body length!

Main author Gene Hunt, a paleontologist at the Smithsonian National Museum of Natural History, analyzes that it is a short-term advantage, since these males may have multiple partners, high mating frequency. , born more descendants and helped their race to quickly increase population.

However, in the long run, " huge " genital organs and "love" lions have taken away so much energy that they become weak.

When the natural environment and climate change, they have no strength to adapt and thus become extinct. This clam is not the only ancient creature that has been found to have a large reproductive apparatus compared to body size.

Researchers believe that this may still be true for modern organisms and help biologists assess which species are vulnerable to changes in the environment - climate and have protection plans. .
