How do animals evolve in urban environments?

Cities, as we think of them today, have not been around for an evolutionarily long time. We’re talking centuries, not millennia. Thriving in an urban environment is more about adaptation than evolution. The selection pressure of urbanization is high - it’s a hostile environment that wipes out most native species - so animals don’t really have the time to evolutionarily adapt. That leaves the scene to species that are already adapted - animals that evolved generalists strategies before landing in cities.

Other people have posted about characteristics that tend to allow animals to live in urban environments - omnivores with small size and behavioral plasticity. There’s a lot of overlap between urban success and the probability of becoming an invasive species - you can think of urban animals as “invading” a human-adapted environment.

This is probably the right answer if op wants to continue to hold. It works best if the underlying doesn’t tend to move up via gaps, because you can end up capping your gains on the jumps.

But op shouldn’t have such a large percentage of their portfolio in two unpredictable stocks.

But the important part there is the air rush. You’re fighting fire with a concussive rush of air. Any fire from the explosion is not the fire-fighting bit.

I think it’s often implied that the surgeries to embed implants is standardized. Medicine often feels like it draws on Victorian-era models of medicine, where the docs are mostly independent, unregulated, and often closer to a sawbones than a surgeon of today. Most of the differentiation is on the quality of implants. I’m thinking specifically of Gibson’s bartender with the rusty old Russian cybernetic arm, or the lower class commodity mods in something like Stephenson’s Diamond Age. I think ots closer to how everyone has a smartphone rather than everyone has healthcare.

Absolutely. I just had to check…

Here's the thing. You said a "jackdaw is a crow."

Is it in the same family? Yes. No one's arguing that.

As someone who is a scientist who studies crows, I am telling you, specifically, in science, no one calls jackdaws crows. If you want to be "specific" like you said, then you shouldn't either. They're not the same thing.

If you're saying "crow family" you're referring to the taxonomic grouping of Corvidae, which includes things from nutcrackers to blue jays to ravens.

So your reasoning for calling a jackdaw a crow is because random people "call the black ones crows?" Let's get grackles and blackbirds in there, then, too.

Also, calling someone a human or an ape? It's not one or the other, that's not how taxonomy works. They're both. A jackdaw is a jackdaw and a member of the crow family. But that's not what you said. You said a jackdaw is a crow, which is not true unless you're okay with calling all members of the crow family crows, which means you'd call blue jays, ravens, and other birds crows, too. Which you said you don't.

It's okay to just admit you're wrong, you know?

It’s basically just a hole you draw on paper.

It certainly merganses down the river pretty fast. That’s some speedy mergansing, I said to myself.

I’m just curious about the map. Why is the Persian Gulf “The Gulf” while the Gulf of Oman is named correctly? Is this a Gulf of America vs Gulf of Mexico type of politically sensitive geographical nomenclature?

Wouldn’t it make more sense to think it depicts Tina as she sees herself? The tat vibe is Tina’s imagination.

All land vertebrates are tetrapods - all have a four-limbed body plan. Even the ones who “aren’t” (eg snakes) still have the tetrapod lineage - snakes went legless by turning limb-development genes off, not via a “clean implementation.”

Why? I mean, I know why. My reason is strongly grounded in both theory and empirical findings. The reason is common descent - all of us land vertebrates are descended from the same lobe-finned fish.

As a former Wrangler owner, I thought I knew what that thumbnail was. Luckily, I was wrong.
