I’ll hold off too because some feathers grow straight from the bones. Eek
Huh? I just read this book and that was not in there. The kids just drank a potion and then could fly, there was no outward difference to them. Maybe you are mixing up a different one, like the chicken one? We just started that so idk how it goes. The cover has the girl as a chicken though.
Just need two chickens, a dispenser, and a redstone clock for infinite chickens

What does that even mean, you have like “four letters” and dna strands of millions long. Like how selective do you have to be. I’m sure you can basically write anything that way.
Are there entire chunks that are inactive that would give feathers, that at some point gave feathers to our ancestors?

I agree, this seems pretty misleading. And are there any other feathered animals other than on the dinosaur branch? Because if not, how should the feather DNA even end up in mammalian DNA?? Or maybe feathers are produced by very common differently used genes? But in this case this would be even more nonsensical…
DNA contains coding and control regions. Changes to the coding regions are rare, most of the evolutionary stuff is happening within those control regions instead. Mutations there are more likely to result in interesting effects by affecting the way genes activate and interact, while the coding regions do the heavy lifting.
Losing some feature could be as simple as a mutation that permanently switches off the control region of a gene, even if the gene itself and the interactions formerly coded around it still work. Over time, those accumulate mutations and degrade, since they are not useful and therefore evolution doesn’t preserve them, but they are still there. For example, we have an inactivated gene that used to make an enzyme that would break down uric acid. So we get gout, but our ancestors didn’t.

All things DNA is full of code that doesn’t get activated and is just passed on anyways
Gene expression is what they mean by “activated”

Yes. Burgerlanders are very averse to any level of self improvement that might be difficult. I blame the car culture propaganda more than I blame the people though.
I know I’m China brained, but go to a park in China and you’ll have a hard time walking the paths because of the number of people running, and the squares will be filled with people paying badminton and dancing.
It shamed me into exercising regularly.

There’s just something about stairs that gets me. I can run a sub hour 10k, hike 15+ miles a day, and my resting heart rate is in the 50s, but stairs always get me winded.

My french teacher in high school said that everyone gets winded going up stairs, cause people who are fitter walk up the steps faster
This just solved it for me. That is exactly it. I’ve been angry at stairs my whole life and now I realize it’s because I go up them as fast as I walk- which is considerably faster than most people I know.
Stairs are different muscles. I used to work at a dam where I would have to climb 20 flights of stairs/ladders multiple times a day with 80 pounds worth of tools on me. Before then stairs were difficult for me, now I can run up that with that much weight no problem. I haven’t worked there for a year but I also can do sub hour 10k (barely) but those muscles stay with you as long as you stay on your feet regularly during the day.
If it’s an issue for you I suggest weight training up and down the stairs you have available to you (in your house maybe?) 5 minutes a day with a couple 20 pound weights up and down those bitches and you’ll make walking stairs your bitch for the rest of your life. If you can do a sub 10k you have the willpower to do it if you want to.

this is literally how it works for birds, that’s why you see especially pidgeons and corvids walking so often, they just don’t need to fly a lot so they simply walk.
I say this without doing any googling (big risk) but I’m pretty sure everyone has them - they’re the lines along which your skin originally formed in the womb. Or where your skin currently grows and migrates from. Or both. Maybe I should have googled lol
Unless you have the right skin condition I don’t think they’re visible in any wavelength

Why would I dye my hair when plumage is an option?
I feel feathery
Oh, so feathery
All my plumage is standing up tall
Yeah, just leaves more plumage for me to dazzle the ladies with. Have fun not passing on your genes because i have the superior plumage.

Ahh I checked the synopsis and you’re right I definitely got it mixed up with another. I need to find it now.

I recall that scientists reactivated chicken genes for teeth and grew a toothed chook
If people had wings and could fly it would be considered exercise and nobody would do it.
Americans wouldn’t do it, the rest of the world would
Yes. Burgerlanders are very averse to any level of self improvement that might be difficult. I blame the car culture propaganda more than I blame the people though.
I’m tall and fairly light. Skipping steps helps a lot with efficiency.
Yeah one time I traveled to Europe and everyone was just running everywhere. Very efficient.

In America it’s a lot of white, black typically winds up on skid row or at the morgue.

Why would I fly for twenty minutes when I can drive for an hour 🙄
If you look at birds like the kakapo, they would’ve had flight in the evolutionary past, but evolved out of it due to lack of predatory threat.
This can be part of Island syndrome, where the dodo also suffered from, till sailors came around and found out they were tasty.
We’d end up making flying cars so we wouldn’t have to fly ourselves…
this is literally how it works for birds, that’s why you see especially pidgeons and corvids walking so often, they just don’t need to fly a lot so they simply walk.
That can be dangerous in the long term.
