How the Dinosaurs Really Died
Many scientists and intellectuals think that dinosaurs
died when an asteroid smashed into the Earth millions
of years ago. However, recently, there has been some
controversy over this theory. Some scientists think
that it isn’t accurate. They think that a tiny insect may
have been the biggest factor in the death of these
huge creatures. That insect was the mosquito.
Ml - * These scientists do think that an asteroid hit the Earth
the time of the dinosaurs. But that wasn’t what killed all of them.
At that time, insects, including the mosquito, were beginning to evolve. Today, we can
regulate the number of mosquitoes with pesticides. But that was impossible millions
of years ago. The mosquitoes multiplied quickly. And they were certainly not idle. Since
there were so many mosquitoes, it was easy for them to bite many of the dinosaurs.
When they bit another living thing, the mosquitoes passed along a deadly disease. So the
dinosaurs were stricken with the disease. A vast majority of them, from the vegetarians to
the meat eaters, died.
To reinforce this idea, scientists stress how gradually the dinosaurs died. If an asteroid
ifc*- • killed them, they would have died very quickly. But the number of dinosaurs decreased
slowly. In addition, scientists have found genetic material of mosquitoes in fossils. This
material proves that mosquitoes existed back then. Although there may have been other
factors, the dinosaurs died mainly because of disease, the scientists say.

things. Many dinosaurs ate mammals. After the dinosaurs died, mammals were able to

evolve and produce offspring. Birds also evolved. Scientists have analyzed the genomes of
birds, and they discovered
that birds have identical
genetic material to some
dinosaurs. So there may
still be dinosaurs among
us after all.
