Evolution of Malaria is being speculated from the era of dinosaurs!

Evolution of Malaria is being speculated from the era of dinosaurs!

A new study has refuted all the thoughts for calling malaria a disease to be developed in the tropical area. Apart from this, this study has also revealed that the vertebrate hosts that evolved firstly and are responsible for the deadly disease may also have been involved the gigantic species of the dinosaurs. The disease Malaria is thought to be of the exclusive modern origin and its causative agent is Anopheles mosquitoes.

According to George Poinar, from Oregon State University of US the ancestral forms of this disease used different insect vectors and malarial strains, and may have helped shape animal survival and evolution on Earth.

Poinar also pointed out that this fatal disease which can infect animals ranging from humans and other mammals to birds and reptiles, may have begun in an insect such as the biting midge more than 100 million years ago. These could have played a major role in the extinction of the dinosaurs.

The primary hosts of the diseases here are insects as the sexual reproduction stage of malaria only occurs in them. The evidence from the study also points towards Gregarinida, a protozoan parasite group that could have been the progenitors of malaria, since they readily infect the insects that vector malaria today. This study further can help us to understand the modern day life cycle of malaria, its evolution and much more. The study was published in the journal American Entomologist.
