Cockroaches: Masters of the kitchens of the world

Cockroaches are one of the most successful creatures on the planet. They have lived on Earth for millions of years and are able to survive in a wide variety of conditions. But where did they come from and how did they manage to spread so widely?

A new genetic study published in the journal Livescience  sheds light on the history of cockroaches. Researchers have analyzed the DNA of cockroaches from around the world and found that they all come from a single species that originated in South Asia more than 300 million years ago.

From South Asia, cockroaches have spread around the world thanks to trade and human travel. They are synanthropes, that is, they live next to people. Cockroaches thrive in human dwellings where they have access to food and water.

The study also found that cockroaches have evolved over time to become more resistant to insecticides. This makes them even more difficult pests to control.

Although cockroaches are often considered pests, they also play an important role in the ecosystem. They are a source of food for many animals and also help decompose organic matter.

A new genetic study of cockroaches is a fascinating journey through time that helps us better understand these unique creatures. The study also highlights the importance of understanding the evolution of pests in order to develop effective methods for their control.
