How did the cockroaches escape from the asteroid that led to the extinction of dinosaurs? Kinkal, age 11, Delhi, India
When the rock is now known as the name Chicxulub Impactor He decreased from outer space and criticized the Earth 66 million years ago, the cockroaches were there. The influence caused a huge earthquake, and scientists also believe this The outbreak of my volcano Thousands of miles from the impact site. Three quarters of plants and animals died on Earth, including all dinosaurs, Except for some species Who were the ancestors of birds today.
How can cockroaches remain a few inches alive when many strong animals became extinct? It turned out that she was well equipped to live through a meteor disaster.
If you have seen a cockroach before, you may have noticed that their bodies are very flat. This is not an accident. Permanent insects can press more strict places. This enables them to hide practically anywhere – and may help them survive in the Chicxulub effect.
When the meteorite is beaten, The temperatures rose on the surface of the earth. Many animals have no place to escape, but cockroaches could heal in small soil cracks, which provide excellent protection from heat.
Meteorite It raised a series of antiquities. A lot of dust set out that the sky is dark. As the sun concludes, the temperatures decreased and the circumstances became winter all over the world. With a little sunlight, the remaining plants struggled for growth, and many other organisms that relied on these plants were hungry.
No cockroaches, though. Unlike some insects Prefer to eat a specific plantCockroaches Zabon. This means that they will eat most foods that come from animals or plants as well as cardboard, some types of clothes and even a tube. The presence of an appetite is not difficult to satisfy, allowing cockroaches to survive in times of lean because Chicxulub and other natural disasters.
Another useful feature is those cockroaches Laying their eggs in small preventive cases. These white cartoons look like dried beans and are called othecae, which means “eggs”. Like telephone cases, Oothecae is difficult and protects their contents from physical damage and other threats, such as floods and dehydration. Some cockroaches may have waited part of the Chicxulub disaster from Oothecae.
Modern cockroaches are young survivors who can live anywhere on Earth, from the heat of tropical regions to some of the most severe parts of the world. Scientists can There are more than 4000 types of cockroaches.
A handful of these species loves to live with humans and rapidly become pests. Once the cockroaches arise in a building, it is difficult to rid each small rift of these insects and othecae. When large numbers of cockroaches are in unhealthy places, they can spread diseases. The biggest threat to human health is one of the allergic substances that can Directing asthma attacks and allergic reactions In some people.
It is difficult to manage cockroach pests because they can Resistance to many chemical pesticides And because they have the same capabilities that helped their ancestors exceed many dinosaurs. However, cockroaches are much more than the scourge for control. Researchers study cockroaches to understand How to move and How their bodies are designed For ideas for building better robots.
As a scientistI see all the beautiful insects, six legs. Cockroaches have already overcome the possibilities that were very large for dinosaurs. If you hit the last meteorite, I will be more anxious to humans than cockroaches.
