How Snake Venom Sparked An Evolutionary Arms Race

For some, the rise and spread of venomous elapids was just another challenge to adapt to. For others, it was a catastrophe of almost apocalyptic proportions. And we humans are no exception, because it seems that when elapids slithered onto the ecological scene, not even our ancestors were safe…

It often strikes me when we say something like "the species developed resistance to this" that it really means "a whole lot of the species died." The way we say it so often implies that individuals are sitting around strategizing and planning how to evolve. We even sometimes say "evolutionary strategy." But it's actually that a whole lot of individuals died out and a few survived through a lucky fluke that was then passed on.

@lonestarr1490 2 ай бұрын

Exactly. Life persists only through dying. An incomprehensible amount of dying. Taking everything we consider alive into account, every second that passes was the very last in the life of billions upon billions of individuals.

@lonestarr1490 2 ай бұрын

@@oldcowbb While there is no agency, there certainly is causality and reason. Hence, talking in these terms is not completely unjustified, albeit potentially misleading as it presents it the wrong way around. A bit like, "It is, therefore it must be". The other, probably even more challenging aspect there is to it is the limitations of language itself (which certainly stems from the modus of perception you already pointed out). Personification of inanimate aspects of reality is not always a mere stylistic choice, but might sometimes become a necessity, especially when you're trying to jam-pack as much information as possible into a 10 minute long video, or---in stark contrast to the verbal debauchery I'm currently indulging in---strive to keep your sentences short. Sometimes being comprehensible is simply more important than being precise.

I came face to face with a Mozambique spitting cobra on a river bank when I was a little kid. It was fixing my gaze looking up at me and I was staring back, no idea I was in any danger. Luckily a local man saw what was happening and ran over shouting, he hit the snake with a stick and explained to my parents what it was. Venom in the eyes is not as harmful as a bite but still frightening and painful and occasionally blinding. The bite is dangerous as it is very venomous. Poor wee snake was probably just nervous and scared.

I think another interesting point in this "arms race" is that Austrlaian taipans, which are an asian species originally, and possibly related to sea snakes, have a venom that is SPECIFICALLY DEADLY to PRIMATES... except... Australia HAS NO primates... so their venom's evolution was a direct response to pressure from Australia's indigenous HUMAN population.

@olwynskye417, there is no such thing as an elapid, Elapidae is no longer a valid family, it is now replaced with five different families that are mostly not closely related to each other, which are Micruridae (Coral Snakes), Hydrophiidae (Sea Snakes), Acanthophiidae (Oceanian Asps), Bungaridae (Land Kraits and African Garter Snakes), and Najidae (Cobras and Mambas), Elapidae is no longer recognized because its original type genus Elaps is invalid, harlequin snakes are now thought to belong to the family Atractaspididae with their original genus Elaps now being renamed Homoroselaps, for this reason, the Elapidae family is now abandoned.
