Which plumbing parts can only be made with plastic? We had plumbing long before plastic.

I had this on my wall as a kid. Pretty awesome. https://www.muralsyourway.com/earthrise-mural/p?idsku=2356&popup=true&keyword=&gclid=Cj0KCQiAn4SeBhCwARIsANeF9DLt-EK_QBgLW8eRG3mDNd4K3DujK1bi_1eRQei996-m3HKJMoQ6qiMaAsAzEALw_wcB

That’s not how mitochondrial DNA works. It is passed from mother to offspring 100% intact. Unlike nuclear DNA which mixes and you can end up with a “tiny bit”, mitochondrial DNA is all or nothing.

Multiple smaller bombs are more effective. At a certain point, bigger isn’t necessarily more effective.

Uh, no. That’s not “newer theory” you are talking about Lamarckism which was debunked a long long time ago. Stretch your neck all you want, it isn’t going to change your DNA and there is. I way to pass that to your kids genetically.

Yes, it is natural selection. You probably learned about the peppered moth in school. Pretty famous example. https://en.m.wikipedia.org/wiki/Peppered_moth_evolution

Basically the area was so polluted with soot during the industrial revolution that the dark form of the moth was better adapted to survive on the dirty surfaces in town.

Yes, selection can also cause two hazardous species to end up looking like each other as negative interactions with either species is beneficial to both. Monarch butterflies and Viceroy butterflies are an example.

The example you cited with hover flies is Batesian mimicry while the butterfly example is called Müllerian mimicry in case someone wants to learn more.

The “why” comes down to evolution. Let’s do a thought experiment. There is a population of caterpillars that are poisonous. They look exactly like a non-poisonous species and both are mostly brown. Birds will try to eat both. They notice that some taste great and some taste awful.

Which is which though? You don’t want to make the same mistake twice. There is, of course, genetic variation in coloration. Some of the poisonous caterpillars have small, thin red stripes and some don’t. The birds eat both and notice that all of the ones with red stripes taste bad but only some of the all brown ones taste bad (because some are poisonous and some are the non-poisonous species). They stop eating the striped ones but keep eating the brown ones (and spitting them out). The poisonous ones with no red stripes are thus weeded out of the gene pool and all of the poisonous offspring now only have red stripes. Over time, those red stripes get larger and larger as the caterpillars with bolder red stripes are less likely to accidentally get eaten and thus the genes for bold bright warning colors are more likely to be spread in the gene pool of poisonous animals. The opposite is true for tasty non-poisonous animals. Only those with the best adapted camouflage survive to pass their genes onto the next generation.

I’m old enough to remember when cable was sold to us as the “ad-free” option to get away from broadcast TV that was cluttered with ads. Didn’t take too long before cable was waaaay worse with more ads than broadcast TV ever had.

Based on the ads they currently show me, they don’t know a damn thing about me.

It is an interesting thought but for the sake of brevity I did not include all of the details in my post. Every time I have seen this happen it was when an osprey was being chased by a bald eagle. They did not want to drop the fish but they had to in order to use their talons to defend themselves. So, I don’t think it was intentional to drop them in the lake. At another location I have found fish in the middle of a baseball field presumably dropped by osprey as well under similar situations.

A couple other ways I have personally witnessed. Spring flooding can create creeks between lakes and I have witnessed fish swim between them. I have also watched osprey catch full grown fish and accidentally drop them into other lakes. It seems like a freak accident but I have witnessed it multiple times.
