New Delhi: Often thought to be the source of modern, malaria can be evolved in prehistoric times, a study claims. USA Oregon State University study, malaria could be evolved at least 100 million years ago, prehistoric insects.
This study is the first vertebrate hosts more severe disease may include dinosaurs. The research so far, contradictory as the old one, 15,000 to 8 million years old malaria protozoa, primarily caused by the Plasmodium genus is considered to be one, and spreads by anopheline mosquitoes.
Ancestral forms of the disease in the United States and the varied species of insect vectors of malaria are used and shape the evolution of animal survival and may have helped the world, according to George Poinar, from Oregon State University.
Poinar suggested that this deadly disease, which today from humans and other mammals, birds and reptiles can affect the emergence of small animals, more than 100 million years ago, such as an insect may start biting Midge.
Prior to the extinction of dinosaurs, researchers and malaria can play an important role in the blood-sucking insects as well as the evolution of the disease vector was involved.
“The fossil evidence shows that at least 20 million years old, the modern malaria vectored by mosquitoes, and the previous form of the disease, midges biting carried out at least 100 million years old and is probably much older,” Poinar said.
Sexual reproduction of the malaria occurs only insects, they are the primary hosts of the disease, not only vertebrates that they must be considered infected with disease-causing protozoa, Poinar said.
Malaria is a protozoan parasite group that may contain evidence of progenitors, since they readily infect insects as vectors of malaria Gregarinida indicated that today, he said.
Malaria understand the evolution of ancient history, Poinar said, modern-day life cycle of how it works, how it evolved, and what is its most common vector, Anopheles mosquitoes to interrupt the transmission of the possible targets that can give clues.
According to the evidence of insects preserved in amber is also found in understanding the evolution of malaria worldwide journey takes one. The study was published in the Journal of the American entomologist.
