Wouldn't a mutation in the deer sight to see orange be vastly evolutionary beneficial?
It's been far more important, evolution wise, to be agile and quick enough to avoid predators. Like a security camera can only tell you how someone was murdered.
Only in areas with tigers, and then it would only express itself enough if there were enough evolutionary pressure exclusively on that survival tactic.
As long as other causes of death happen to deer in tiger territories and as long as speed remains a good survival strategy, minor mutations that would only provide an advantage in extreme specific scenarios like a tiger stalking them wouldn't have a chance to be spread.
There's also a whole host of additional brain power that needs to be dedicated to more complex colour blending and processing, and that may add enough delay to offset any potential gain in recognizing a threat.
And then soon we'd have green tigers.
There are no green mammals because of some biology reason I can't remember.
Basically all mammalian pigmentation is just melanin, so mammal colorings are mostly just different amounts of brown combined with different amounts of red, and some animals don't even have the red.
Yeah I think it was a balance patch, because mammals that could photosynthesize were too OP.
Presumably yes, but its still down to a roll of the dice whether a mutation like that happens in the first place, and whether the individuals who have that mutation live long enough to breed, and whether that mutation actually gets passed down, etc
It could, but it might also lead to something harmful for the deer at the same time. I'm not sure if the gene affecting the deer's eyesight is known, but it could be a pleiotropic gene (a gene that influences multiple traits at once).
If that's the case, and the other effect is negative and somehow spreads through the population, it could become a future issue for the deer. Think about humansβwe lost the ability to produce our own vitamin C. Almost every other mammal can produce their own (except for hamsters). When this happened, it didnβt harm us right away, so it spread through the population. But over time, it led to issues that werenβt a problem before, like scurvy.
Same could happen to the deer.
This kinda makes Lord Vetinari a little less cool tho...
Still pretty fun fact.
Do the tigers know they are orange?
No, they too are dichromats
Do humans know tigers are green?
Asking the real questions
Probably not, the same way humans don't know we are striped.
Ist is possible to make the own pattern visible? Like with special Cameras and Light?

Desperately need me a community just for tiger facts like this and pictures of tigers. Greatest of the Big Cats
Thank you for subscribing to Big Cat Facts
Feel free to open !bigcats or !tiger I'll be your first follower.
I wish lol. I don't have enough time to manage a community though. if someone else made one though i'd follow it instantly
I vaguely remember someone mentioning a community to give your community ideas to who may want to implement it... I forgot the name.
Would not green be the obvious route then?
AFAIK green is more expensive to produce. Plants use it since it's good at absorbing sunlight, but what's the advantage to a tiger, if their prey can't tell the difference?
This must be utterly terrifying for them.
"Why? I've always been orange." - tigers
Almost like our eyes evolved to give danger its own colour.
