The Timema stick 'rests on the pillow' for 1 million years

Genetic researchers have revealed the Timema rod insect that lives in the dirt around the west coast of the United States that has lived for 1 million years without ever "moving".

By analyzing DNA, scientists believe that this asexual insect has existed for a long time, 500,000 years ago, even having a longer life.

Even though there are still males, the Timema does not " move the room " but gives birth to itself. Dr. Tanja Schwander of Simon Graser University, Canada, told the BBC: ' We have most of the evidence to prove that males and females have existed for more than 1 million years without any sexual activity. .

In a study of sexual reproduction and asexual reproduction, scientists claim that asexual reproduction does not bring a certain benefit, not to mention the rapid increase in quantity. , even repeated gene cloning is considered a negative consequence and proves that this species is poorly adapted to the environment.

Dr. Schwander said that not any asexual species is quickly extinct and there is currently no evidence to explain the long-term existence of the rodent bug Timema. It is known that the focus of scientists' research is the negative consequence of asexual reproduction.
