How have humans evolved to see multiple colours?

Question

What use are all these colours in our evolutionary survival?

Humans evolved like a presence selves (evolutionary-wise) before civilisation, whilst we were still hunter gatherers?

I don't think having the opportunity to see colours does us any harm though, but have they ever been essential?

Answer 1

We have fruitivore ancestry. Color vision is quite an adaptive advantage in perceiving the ripest fruit. Even a slight adaptive advantage( as little as 1% coefficient of fitness advantage ) would allow some to out compete others and leave more decedents.

Answer 2

Evolution doesn't work by necessity, it works through opportunity. Colour vision has never been essential but animals with colour vision are more likely to survive than those without.

Colour vision allows hunters to spot their prey more easily and avoid their predators. Colour vision allows gatherers to tell the difference between plants and fruits at a glance, especially important for avoiding poisonous foods.

Answer 3

the whole point of evolving is its just that - slow changes.
animals see in shades of grey mostly and hunt by watching movement and using scent. this helps to compensate for lesser visual awareness than people say. im sure the first people couldnt see in colour and were at an immediate disadvantage when it came to spotting prey.
so eventually someone developed eyesight where they could make out some colour. this happened through an actual mutation in their genes and this event benefitted them. then those people with colour vision bacame more successful and competitive than their mono-vision neighbours and flourished.
the colour-blind's decreased and today most people see in colour.

Answer 4

the ability to see colour we evolved it so that we could tell the diffrence in colour between poision and normal berrys ect witch had been like that because other animals had evouled colour vission b4 we did also to tell if a potentioal mate is well and the abilty to see colour would help a early human or primate what ever to see the member of the opposite sex that blush`s that used to be a give away of attraction and hence more likly to mate more likly to get your d.n.a passed on and hence most people will end up with it anything that makes you more likely to mate and have offspring is evolution some times that means living shorter some times longer depens on the life forum and the time ect why did human`s evolve to do it doggie style cos monekys can do it easy with out coming out of a tree all these years later and with out any other help doggie is still probably the easyst and quick`st way to have sex sorry gone off of colour vission here but there are loads of resons why it would be more likly for the colour seeing early humans or what ever to mate if they saw colour and hence thats why we all see in colour same sorta reason why your eyes are in your head insted of you chest it just works better for you if its like that . if my rant is any help sorry if i got a bit long wind`ed

Answer 5

The general answer to this one is usually full of microscopic jargon & particles. But the human ability to see colours is shared with a number of other animals, decided by how the eye came to function.

How does it benefit us? We have survived by hunting well camouflaged animals.

Answer 6

Apart from all the text-book scientific answers to this question; do you not think that our world and our lives would be very dull and drab if we could not see the beauty of colour?

Answer 7

of course colours are important. You'd get a stomach ache if you ate a berry which wasn't ripe.

Answer 8

Lysergic acid diethylamide, commonly called LSD, acid, or LSD-25, is a semisynthetic psychedelic drug. The short form LSD comes from the German "Lysergsäure-diethylamid". A typical single dose of LSD is between 100 and 500 micrograms, an amount roughly equal to one-tenth the mass of a grain of sand. Threshold effects can be felt with as little as 20 micrograms[1] but most users may prefer to take larger doses.[2]

The effects of LSD can vary greatly depending on factors such as previous experiences, state of mind and environment, as well as dose strength. Generally, LSD causes expansion and altered experience of senses, emotions, memories, time, and awareness for 8 to 14 hours. In addition, LSD may produce visual effects such as moving geometric patterns, "trails" behind moving objects, and brilliant colors. LSD does not produce hallucinations in the strict sense but instead illusions and vivid daydream-like fantasies, in which ordinary objects and experiences can take on entirely different appearances or meanings. At higher doses it can cause synesthesia. Some users cite the LSD experience as causing long-term or permanent changes in their personality and life perspective.

LSD is synthesized from lysergic acid derived from ergot, a grain fungus that typically grows on rye. LSD is sensitive to oxygen, ultraviolet light, and chlorine, especially in solution (though its potency may last years if the substance is stored away from light and moisture at low temperature). In pure form it is colorless, odorless, and mildly bitter. LSD is typically delivered orally, usually on a substrate such as absorbent blotter paper, a sugar cube, or gelatin. In its liquid form, it can be administered by intramuscular or intravenous injection, or even in the form of eye-drops

Introduced by Sandoz Laboratories as a drug with various psychiatric uses, LSD quickly became a therapeutic agent that appeared to show great promise. However, the extra-medical use of the drug in Western society in the middle years of the twentieth century led to a political firestorm that resulted in the banning of the substance for medical as well as recreational and spiritual uses. Despite this, it is still considered a promising drug in some intellectual circles, and organizations such as MAPS, Heffter Research Institute and the Albert Hofmann Foundation exist to fund, encourage and coordinate research into its medical uses

God made flowers different colors so eve would like them. adam picked her a bouquet and she was very grateful and she showed him how much. You know the rest of the story.

Answer 10

There is no evolution. We did not come from a monkey. God created our eyes to see lots of colors so that we're able to enjoy the world around us to the fullest extent. We aren't an accident that resulted from a explosion millions of years ago. We were created by an inteligent desighner to see with all the colors we see. I know this will stir things up a lot and make you and lots of other people really mad by posting this, but it's the truth.
