There’s likely some cases of convergent evolution, but I’m not sure this is settled for all trees.

I’d suspect that at least some trees with last common ancestors that are shrubs have re-enabled genes that enable the tree phenotype rather than independently evolving the tree phenotype.

But still really cool (and maybe turns on exactly how much evolution your consider needs to happen before it’s convergent evolution.)

Because they temporarily block the onset of puberty, not permanently block it. Any effects are mostly reversible if the individual desires. What isn’t reversible are the all too frequent side effects of untreated dysphoria: death.

Not consenting to a police search doesn’t stop the search, and that’s ok.

What it does is make the fruits of that search inadmissable, and may also enable you to sue them if the search was unreasonable or excessive, or the pretext violated your rights.

Even if you know you don’t have anything in your car, verbally and clearly say that you don’t consent to the search, and would like them to note that fact, but otherwise comply. Lots of people have been caught up by police planting evidence, and you don’t want to be one of them.

Depends heavily on the kind (and intensity) of radiation. Beta (electron/positron) and gamma (photon) generally won’t, but neutron and alpha can. Many of the atoms that become radioactive will rapidly decay, and that’s one of the mechanisms behind the impact to structural integrity.

That didn’t work out so well.
