The study still leaves many questions unanswered, and yet study such as this lays the groundwork for further discoveries in simultaneously medical and evolutionary industries. So next time you encounter a snake, remember : it's not just a hiss, but the best complex, centuries-old system hiding inside plain sight.By evaluating the genomes of 23 different snake species, researchers discovered the variety of genes and proteins that may affect a venom's toxicity and function. As an example, many venoms include neurotoxins that target the stressed system, while others may perhaps include hemotoxic compounds that destroy red blood cells.
