How Viruses Evolved

If I have used artwork that belongs to you but have neglected to credit it this will just be because I was unable to find one. If this has happened please contact me and I will add a credit.
Some Art work has been altered for the purposes of bettering them for video format; these alterations were done independent from the artists who created the original work, so they are not responsible for any inaccuracies that could have occurred with the changes being made.

Viruses are tiny and are often not even considered to be living but they still have a massive impact on life and life’s history, in fact they may be so historical that they predate cellular life.

It's insane how something so small and simple can have such a big impact on the world

[tobiasboh]

Viruses be like "I'm going to seize these means of reproduction"

[nesslig]

Every evolutionary biology youtuber now be like
*"mmmh...perhaps I should be talking about viruses in my next video"*

[aetherslugstar]

There are even some viruses that infect other viruses. That's a fact that's true nightmare fuel.

I'd really love to see a video on extinct mammalian groups such as the multituberculates, (or any other extinct mammals which can't be categorized as placentals, marsupials or monotremes)

Don't forget prions which are smaller than viruses and can replicate without genetic material.

I've been a fan since this channel started. You've really improved dramatically. It's cool to see the little changes from video to video. You're doing everything right. I hope it pays off for you.

Fascinating stuff! I’m glad I found this channel, I’ve been binging on your work all morning haha

[stephenspackman]

I favour the theory that they are (relics of) an ancient horizontal gene transfer mechanism, not predating the cell, but predating what we would now call a “species”.

Feel like you should've mentioned that arguably the main reason viruses aren't considered living is because they lack homeostasis. You brought up the blurred line of living vs chemical and even attributed it to them not self-replicating but didn't mention homeostasis

[BenjaminISmith]

There is no line between life and chemistry. It's just more useful to say that animals, plants, and things like that are different than rocks, air and water

I can't believe I've been watching SciShow and Eons for years and YT never showed me this channel until recently

[awilliams]

@10:18 wow, Ken Ham is a Patron... I know it's not AIG Ken Ham, but it'd be funny if it was 😅

[Pahjx]

I didn't know viroids were a thing, it really does blur the lines between life and chemical reactions.

So could that wasp virus possibly be adapted to help organs from being rejected during organ transplants?

[nickpater]

Early life and evolution in general is such an interesting topic! I was thinking of finding some nonfiction books to read on this. Anyone here have good reads about this kind of stuff?

[tonyballerxxxx]

This reinforced my theory that wasps are pure evil little creatures.

[rodrigorosatoalves]

Great video! And thank you for the size comparison. It really helps to put things in context! I guess it wouldn’t hurt to be a bit more specific about the examples. Like... a coronavirus, a red blood cell, an E. coli and so on. Things commonly known by the average Joe and Jane lol

[NORTH]

I’ve been thinking about making a video like this, good stuff!

[sheikowi]

I'm amazed that during the current plague, millions have not viewed this video. I wonder how many of the covid spokesmen & hawkers have even the basic info contained herein. Keep up the superb superb work!
