Documented deaths resulting from snake bites are uncommon. Nonfatal bites from venomous snakes may result in the need for amputation of a limb or part thereof. Of the roughly 725 species of venomous snakes worldwide, only 250 are able to kill a human with one bite. Australia averages only one fatal snake bite per year.
Snakes originated about 120 million years ago. Early snakes had vestigial limbs, with the oldest-known fully limbless snake living around 85 million years ago, according to George Washington ...

Pythons are poached for their meat and skin, leading to a billion-dollar global trade. They can carry diseases, such as salmonella and leptospirosis, which can be transmitted to humans.
Additionally, this adaptation makes these snakes adept burrowers. [5] The species is not dangerous to humans, as no deaths or systemic effects from the extremely rare bite from this rear-fanged snake have been recorded.

However, snake experts have dismissed this theory, stating that snakes simply do not rattle as often as laymen expect them to, and that snakes that live near populated areas simply get used to people passing by, only ...
Historically, snake venom was believed to have evolved once, at the base of the Caenophidia, or derived snakes. Molecular studies published beginning in 2006 suggested that venom originated just once among a putative clade of reptiles, called Toxicofera, approximately 170 million years ago. [7]
