Scientists have forbidden living organisms to reproduce at the genetic level

Scientists at the University of California, San Diego and their colleagues have developed synthetic species of flies that

can only be distributed locally. 

Scientists called their development SPECIES(synthetic postzygotic barriers using CRISPR-based incompatibility for engineered species). It could be used for other species, such as disease-carrying insects, the authors say. The spread of genes that limit pests that feed on valuable food crops is another example of the potential application of SPECIES.

For example, it is possible to create a new species of malaria mosquito that is not capable of transmitting malaria, and also will not become a carrier of it when in contact with other mosquitoes. 

The new development offers a way to control populations in a very safe and reversible manner. 

Omar Akbari, assistant professor of biological sciences at the University of California, San Diego and senior author of the paper

The idea behind the creation of SPECIES isencourages the formation of new species in nature. Since members of the same species can diverge from each other due to various factors, a new species may eventually form due to this process.

However, if his representative mates with someonefrom the original group, non-viable offspring may grow. This is due to the biological changes that follow reproductive isolation.
