Do you think evolution came up with the idea to include an immune system?

Question

If evolution came up with an immune system how did it know that we (or any other creature) would need one? Did it know that it came up with viruses and the like? How can evolution reason this out?
(I am looking for a specific answer-- good luck [if there is such a thing as luck]).

Answer 1

Wow.

Answer 2

First of all you are talking about Evolution as if it is some conscious being... it's not. There's no driving force with a plan behind evolution. Early multi-cellular organisms were more of a symbiotic community of single-celled organisms. These worked in concert, each with different goals... this is how the immune system got it's start. Certain cells were good at removing pathogens from the system and so that's what they developed to do. As organisms got more complex the immune cells and systems associated with them did so as well.

Evolution is the non-random expression of randomly occurring mutations. Small changes in an organism, if helpful in securing the organisms survival and selection, pass on to the next generation and continue to develop.

Answer 3

Your concept of evolution is obviusly skewed and you're assuming that it is a god-like omnicient being.... eveolution is just the name of the way all living things change and adapt to their environment.

It cannot reason, it does not think.... cells mutate, it's a fact, and if some creature with a certain mutation can survive better in a given environment, then offspring carrying the mutation will be chosen for reproduction more than the original version, creating even more creatures of this sort and it will eventually dominate the gene pool. Thus the species will have evolved.

All throughout history, when an animal had a stronger tolerence to illnesses, it is obviously more appealing to possible mates. Therefore, the strongest of any species will be bred with to make more of it's kind and have an even better chance of survival than the previous generation.

And through millions, if not billions, of years of this happening our immune system has developed and will continue to develop.... and those of us who are weak and fall victim to disease easily will die off sooner than our more disease tolerant counterparts.

It's just the way life works.

Answer 4

See, this evolution thing, it is responsible for everything, except it seems as one poster put it...life. Life was created by nature. So let me get this right.....
nature created life the little cell in the ocean that became a fish;
that grew legs;
that learned to breathe air;
that went on land;
that became something other than fishlike to create not only all the animals as we know it, but humans too;
miraculously somehow from that original BIG BANG from matter that got created by something nobody knows where;
and made humans who are the only thing out of all things in this world with the ability to speak, reason, have a concience etc.
We know all this to be true, because man, who is infinitely wise, has gotten together and interpreted things to the best of their belief (as stated by the Berkley evolution site), found some others who will agree with them, suppress those that do not agree with them, and present it as fact for all the little sheeple to blindly quote what they read in a text book.
Yeah, um that makes perfect sense to me.
The One True God IS the only answer in all things.

Answer 5

Evolution is not a person, and did not "reason anything out".

I started typing an explanation of immunities, and how they probably developed, but if you think evolution is a person, I'm probably already talking over your head.

Thanks, & have a great day.

Answer 6

Well, people who were unable to fight off bacteria, viruses, etc. died, so it was the people who had the ability to fight illness who reproduced, thus the characteristic was carried on. The people who were better equipped to fight illness mated even more so the function advanced and it eventually became a whole immune system.

That's how evolution works. Need more info?

Answer 7

It is simple survival of the fittest. Those organisms that were better equipped to figth off diease and infection were the ones to procreate and pass on that ability to the offspring.

Answer 8

evolution couldn't even make a cell, it certainly can't make an immune system.

Answer 9

Evolution is a correct theory, it's not something that created life. Nature did that.

Answer 10

Evolution couldn't have come up with anything.

Answer 11

Some invisible super being came up with it all - Does that make more sense to you?
