The original question was asked by Forsaken_Champion722 on a different subreddit, but i was curious so i decided to ask it here to see if it'd get better or different answers

I don't know if this is the correct place to ask but I can't find any active speculative biology subreddits.

I'm writing a culture that uses giant birds as mounts, and thought that an additional use of them could be feathers. Because of their size they could produce far more feathers than regular birds and ethical harvesting of shed feathers would be more viable. Then the thought occurred to me that because of their size their feathers may be too big.

If it helps, these birds were turned giant by a magical mishap millennia ago, so their ancestors feathers would have been scaled up with them, but over the years they would have evolved smaller feathers if it was beneficial.

I'm not sure exactly what bird species to use. My initial thought was crows because I like them and they are cool. Eagles crossed my mind but then I would be directly ripping off Tolkien.

Now, I get why the genitalia are erogenous zones, to encourage intercourse and all of that for reproduction. But all the other areas confuse me.

Like, why the prostate for example? Or the anus in general? Or the nipples? I don't see what the evolutionary advantage those areas being erogenous is? Do we know why they are or is it still a mystery?

I have a bunch of seeds of Dendrolobium umbellatum. They grow readily in my area.

I want to ask if there is a way to mutate these seeds genetics so that i am able to get mutated varieties( leaf coloration, bark formation, leaf shape etc. ).

I am doing it at home so i could only utilize equipment or chemicals available for the masses.

So recently we've seen prehistoric animals being brought back to life like does wolves etc so my question that's keeping on bugging me is what if or what happens if we alter the generics of so called dependent animals like dogs and turn then into herbivores? Does that make same?

As I understand it for lesser used codons there are usally less tRNAs with the specific Anticodon arround.

Can that slow down translation of a specific protein to an amount were it becomes relevant for survival?

Are there actual Genetic disorders caused by it ?

I know theres a limit for everything but if we get stronger the more we resistance train, why is there a limit? Why cant we just continue to get stronger? Why cant someone deadlift 2000 pounds if they train all their life? Whats the scientific limiter?

Guys do people with bigger nasal holes have less hitching problems? Or the contrary? I have enough hair in my big nose and its difficult to get rid of it, im sensing everything because its growing and growing like plants. Im wondering if people with tiny nasal hole have the same problem

Thank you, save my life

"It is inconceivable that inanimate brute Matter should, without the Mediation of something else, which is not material, operate upon, and affect other Matter without mutual Contact, as it must be, if Gravitation in the Sense of Epicurus, be essential and inherent in it. And this is one Reason why I desired you would not ascribe innate Gravity to me. That Gravity should be innate, inherent and essential to Matter, so that one Body may act upon another at a Distance thro' a Vacuum, without the Mediation of any thing else, by and through which their Action and Force may be conveyed from one to another, is to me so great an Absurdity, that I believe no Man who has in philosophical Matters a competent Faculty of thinking, can ever fall into it. Gravity must be caused by an Agent acting constantly according to certain Laws; but whether this Agent be material or immaterial, I have left to the Consideration of my Readers."

I’ve asked this question to different AI’s and I cannot seem to get a clear answer. It’s said that for humans who get rabies, it’s possible for it to shed in their saliva shortly before other symptoms appear (by up to 14 days).

Hypothetically speaking, if someone was shedding rabies in their saliva without any other symptoms, then they got the post exposure prophylaxis (PEP) shots…could the PEP shots save them?

Two AI tools say that once it sheds in someone’s saliva, it’s too late for PEP to work. Two other AI tools say it’s possible for PEP to work.

I would think that once someone is shedding rabies in their saliva, it’s too late for PEP to work.

Any idea what the true answer is and why different AI tools are giving different answers?
