Frightened of snakes? Looks like you have good evolutionary reason to be. Our ancient ancestors were locked in a biological arms race with the deadly reptiles and the fallout affects us to this day snakes science reptiles

Ancient ancestors of humans were locked in a biological arms race with deadly snakes, with the fallout affecting us to this day, new research has discovered.

“Across the board, the African and Asian primates show some level of resistance to cobra venom, which makes sense because they’re living alongside a lot of large cobra species which will readily defend themselves,” Professor Fry said. Professor Fry said lemurs from Madagascar and primates from South and Central America did not have strong reactions to cobra venom, those from Africa and Asia did.

“But no one had ever approached the question from the idea of resistance to cobra toxin, which is what we’ve now shown.”

For almost a decade, Joanne has been followed and filmed. But what happened last year 'really rattled' herOne of the nation's largest racing bodies is under investigation for what injured workers say is its aggressive and unfair handling of workers compensation claims.\n Hmm so it isn’t just the innate cruelty is horse racing we should be worried about. Hired goons too eh? The racing_nsw self management of Workers Comp scheme has always been one out in Australia. Why would you want to do it yourself? The proof is the insurance premiums - how do they compare vs Vic,Qld and SA for example austrainers ? Go figure.
