Some viruses can cause extremely complex results. Eg the rabies virus makes saliva build up in the mouth (so it can be transferred to a new host), makes the host hydrophobic (fear of water means the salvia isn’t being washed away), and makes the host aggressive (likely to bite and spread the virus in the saliva). This is done once the virus becomes established in the host’s brain. Pretty insane.

Herpes, AIDS and hepatitis have benefits against other diseases. However, I'm not sure that I'd see them as advantagous. For example, AIDS (a virus) makes you resistant to sickle cell disease because it changes the cell shape. Both are horrible diseases but you can live a long life (50) with sickle cell whereas an undiagnosed AIDS patient with full blown AIDS lives for 7-10 years with death following in 1-2 years. Getting diagnosed early and receiving appropriate treatment mkaeste difference between a 10-12 year life span and a normal life span.

@honortruth3600 2 жыл бұрын

In order to cause a widespread genetic impact on various species/kinds, viruses didn't necessarily have to immediately mutate the reproductive cells of a common evolutionary ancestor. While no other altered cells could pass their mutations down to offspring, specific viruses which caused the mutations and who populate the bodies of their hosts without triggering immune response, or in triggering a survivable immune response, can be passed to offspring, as well as to other species/kinds sharing the same habitat. The communicable virus can then cause similar mutations in the new hosts, eventually spreading the mutations into reproductive cells. In other words, a viral mutation could plausibly leap between reproductively incompatible mammals.

@Samuel-qc7kg 2 жыл бұрын

Right, although the mutation could be different between the inhabitants of the place the virus is spreading. To pass on the same exact mutation one has it has to be necessarily through gametes. But I like your idea better because it can have more diverse effects on the hosts.

Viruses are smart and we probably wont outsmart them. Vaccines help to keep that current strand in check. Once that virus evolves it will require a new vaccine. Hence flu shots every year.

Hey! I'm a molecular biologist, my field of expertise being early evolution and synthetic DNA constructs. Just wanted to say that I'm glad to see you did your homework well and explained all the more important aspects and theories behind viral evolution, and in an easy-to-understand way too. I myself believe the emergent complexity theory is right, maybe because I used to do a lot of research on really simple insertion elements (very basic DNA sequences that emerge in bacterial genomes and can jump around in DNA). and the way they enable more complex DNA constructs to evolve. As to wether viri are alive - Tough question. On one hand they lack a lot of key features that we define as life. On the other hand, they show behavior associated with advanced life, such as assessing their enviroment and making decisions based on their conditions. Anyway, congrats to your video, it was a treat to watch!

I am a molecular geneticist (I also have a math degree), and I agree this was pretty well done. As for life, there is no question, viruses are not alive. The definition of "life" includes homeostasis. We are scientists, not lawyers. We don't to do the "it all depends on what 'is' is" thing. If we want viruses to be alive, then we need to change the definition of life just like we changed to definition of a planet to get rid of that pesky Pluto.

Many other organisms pick up genetic material from other distant organisms, not just viruses. For instance, endosymbiotic relations usually lead gene transfer. Coincidentally, quite often viruses act as gene transfer vectors between distant organisms that haven't even established a symbiotic relationship. On the their hand, bacteria are specialists at picking up genetic material from their environment or directly transferring pieces of their genetic material to other bacteria, often of very different species.

Whilst i don't know if this is true, here is what i heard/read in the internet: at some point in the evolution (when monkeys turned human), there was something called a cognitive traidoff. There, they lost the ability to remember things they saw for half a second but gained language ( watch kzfaq.info/get/bejne/odqbnbibyMDNlGQ.html for a video about that). *If* this is true, then this probably took many generations, and as language (or perhaps just communication, not every communication is language, as you said) became more important, they also lost this part of this memory for every stop forward in communication.

Perhaps you could take a look at how some modern ones like lampreys, paracitic ants. and ticks came to be. I would also be really interested in learning about some more of the stuff from the cambrian, like ophabia and anomalicaris. Bizzare lifeforms really facinate me. If you could please even just let me know that this is condidered, I would be very thankful, so thanks in advance.

What Dragrath1 said. Parasitism is too broad a topic. PBS Eons tends to cover specific events or specific groups of organisms (in an evolutionary sense, i.e. clades). Then again, the last video was about adaptive radiation, but using the Triassic as an anchor point/example. So parasitism could be covered... but maybe over several videos sprinkled here and there.
