Fossil Discovery Deepening Snake fly Mystery, All Information Required:

Fossil Discovery often help us to know more about the previous models of existence in the world. However, most of the time they enhance the enigma making it more complicated to understand. Recently, A discovery of four new species of ancient insects in British Columbia and Washington state is piling up more misery.

The fossil species, recently discovered by paleontologists Bruce Archibald of Simon Fraser University and Vladimir Makarkin of the Russian Academy of Sciences, are a group of insects known as snakeflies. The snakeflies are deemed to have existed in the world around 50 million years ago.The findings that got published, raised more inquiries about what evolutionary change did the diverse species have during the previous times, and why they live where they do today.

Snakeflies are predatory insects that are native to the Northern Hemisphere. Scientists have withstood their affirmation about the snakeflies’ evolution. They claim that cold weathers are needed for the insects to trigger development into adults, restricting them exclusively to the regions that experience winter frost days or colder.

“The average yearly climate was moderate like Vancouver or Seattle today, but importantly, with very mild winters of few or no frost days,” says Archibald. We can observe the expedition by the presence of frost intolerant plants like palms living in these forests along with more northerly plants like spruce.

According to Archibald, paleontologists found species of snakeflies in two families. Both of the species had previously been thought to require cold weather to survive. The Fossil Discovery unravels the secret behind the existence of the species, and it is believed that the species adapted to the cold weather following the observation of the previous lots.
