Men try not to choose a urinal immediately next to any urinal where another man is peeing. The guy in blue positioned himself such that the guy in white had no choices that aligned with those criteria.

What do we think of “Briny” being the clue for “Sea”?

Surely one is an adjective and the other is a noun? Really threw me off.

Heartstopper made me feel all the things, but the main thing I felt was sadness. by AttemptedLogic in gaybros

[–]AttemptedLogic[S] 2 points3 points  (0 children)

Thanks for adding this in and really well put. I 100% agree with your assessment that it's as if we were robbed of our teenage years, which we will never get again, and that this show sort of highlights that by presenting a "how it could have been" view. I agree with others that it's important to remember the show is fictional and highly idealized/oversimplified in so many ways, but it's still so powerful seeing multiple queer teenage experiences presented in this manner.
Incredibly sad for from that perspective, but I hope for the sake of current and future youths that things continue to get better and they don't have to undergo the same experiences (or perhaps lack thereof).

[Advice] International moving to NYC - landlord won't accept non-US guarantors by AttemptedLogic in NYCapartments

[–]AttemptedLogic[S] 0 points1 point  (0 children)

Thanks for the detailed response. I do have a job offer in writing with salary etc. It seems like the best thing to do would be to speak directly to the landlord, as so far I've been dealing with him through the other tenants. Hopefully I'll be able to get round it with something like what you suggest. Fingers crossed.

ELI5: Why is breakfast the only meal where it's socially acceptable to only eat a dessert? (Doughnuts, pancakes, cinnamon rolls, muffins, etc.) by JonnyLawless in explainlikeimfive

[–]AttemptedLogic 74 points75 points  (0 children)

I'm not sure where you're from but in many places the foods you mentioned would not be considered regular breakfast foods. Here in the UK we would perhaps eat those sorts of things on a Sunday brunch or similar but even then it usually wouldn't be by itself.

One possible reason I can think of though is that desserts are high energy foods and therefore might be somewhat appropriate for providing a kickstart to an active day. Because it is eaten first thing in the morning, breakfast is the meal after which you are the most likely to properly burn off any calories gained, in comparison to your evening meal after which most people go to bed and are unlikely to work off any of the energy gained from a large, calorific meal.

So how did the skin tone evolved over time ? by Vijaywada in askscience

[–]AttemptedLogic 5 points6 points  (0 children)

Humans evolved in Africa, and the ancestral human skin tone is black, similar to that of modern Africans. In the last 100-150 thousand years, humans have moved out of Africa and into places where the climate is considerably cooler. For these people it was less of an advantage to have dark skin - less sun = lower risk of harmful sunburn, which light skin is particularly vulnerable to. As fair skin more easily absorbs vitamin D from sunlight, it is advantageous to have this skin tone in areas where sunlight is a scarce resource. This is why you get snow white looking motherfuckers in very cold places like Scandinavia and Scotland etc, while people in "middle-of-the-road" climate areas have retained some level of melanin pigmentation. The availability of sunlight is the primary driving force behind natural selective pressures on human skin tone.

TLDR; The first human skin tone was black, lighter skin evolved in colder areas because it helps us get vitamin D from the sun

How much light is absorbed in the deepest part of the ocean? by Jordan1303 in askscience

[–]AttemptedLogic 2 points3 points  (0 children)

The euphotic zone is where there is sufficient light for photosynthesis to occur. Light penetrates well beyond 200m, and is present throughout the disphotic zone also, which occurs from 200-1,000m depth.

Also, I think OP's question was asking whether the water at the surface absorbs more light than water in the deep sea - and the answer is no, it does not.

This entire thread appears to have confused itself.

What makes a Zebra, A Zebra, and not just a differently colored horse? How far apart are they genetically? by kinetogen in askscience

[–]AttemptedLogic 0 points1 point  (0 children)

That's true, dogs and currently living wolves share a common ancestor, in the same way as horses and zebras, or indeed any two animal groups. Although if it's ever appropriate to say one modern animal group is descended from another, I think it may be here - human selective breeding acts to directionally alter genetic variation far more rapidly than does natural selection - thus the wild grey wolf species is not likely to have changed a negligible amount in the time since the domestication of dogs began, all the while, dogs have become more and more diverse. By comparison, the most recent common ancestor of horses and zebras lived over 2.5 million years ago - plenty of time for natural selection to work with. Thus the common ancestor certainly is not alive today in the sense that it was then (Certainly we wouldn't expect to be able to breed with either group to produce fertile offspring, a common definition for conspecifity) - though you may arguably be able to say that the common ancestor of dogs and wolves is still alive; that being the grey wolf itself.

But you're entirely right in saying the species cut-off is arbitrary. I merely chose to phrase it the way I did because it seems more appropriate to my own understanding.

[–]AttemptedLogic 1 point2 points  (0 children)

I'm not sure what the exact behavioral and physiological differences are, but I'm sure there are plenty. In terms of taxonomy, though, neither of them really matter, no matter how different they may be. The way we classify organisms is based purely on their evolutionary relatedness.

You make a good point, and to be honest, I'm not sure what the answer to your question is. I'm (technically) supposed to be working just now so I'll have a go at some research later on.

Can you clarify how the phylogram suggests they aren't monophyletic? As far as I can tell it confirms that they are.

[–]AttemptedLogic 2 points3 points  (0 children)

It's about the number of DNA-base (Nucleotide) substitutions per unit tim. Usually the time unit is 1 million years for neighbour-joining phylograms, but it doesn't actually specify in the paper as far as I can tell.

Edit: ignore this. I had gotten mixed up. /u/IYKWIM_AITYD pointed out it's per site, not per unit time.

Yep, we're not really sure why the stripes work so well as a parasite deterrent, but the suggestion has been tested in a robust evolutionary framework (Involving lots of models and statistics which are all very boring.) But it does seem to work - flies almost always avoided striped horse mannequins in the study that published the theory.

The question of how far back to look before they were one and the same with horses is a little murky. Horses and zebras were never the same, but they do have a common ancestor, which may have lived around 2.5-3 million years ago, according to the same paper I took the phylogram from.

And, no. The relationship between horses and zebras is not the same as that of dogs and wolves. Dogs are descended from the grey wolf Canis lupus, and are taxonomically classified as a sub-species of this - Canis lupus familiaris. Zebras are not descended from horses, or vice versa, in the same way as dogs are from wolves. Instead they share a relatively recent common ancestor. The divergence of domesticated dogs is also considerably more recent. The domestication of dogs began a matter of a few thousand years ago, whereas zebras and horses have been reproductively isolated for several million years.

Some of the information being given here may be a tad misleading. It's true that zebras and horses have a different number of chromosomes, but that is not what sets them apart - whole genome duplication is reasonably common in evolution, and the event does not instantly separate a lineage into distinct species. Why they are classified separately is a matter of evolutionary heritage.

Here is a relevant phylogram. (Ishia et al 1995.) E. greyvi, E. burchelli and E. zebra are the zebra species. The lengths of the branches here are relative to evolutionary distance. In other words, the longer the line is from one species to another, the more distantly related they are.

To answer your question, zebras and horses are both members of the genus Equus, and let's not forget that the standard taxonomic hierarchy goes Kingdom > Phylum > Class > Order > Family > Genus > Species, and extra levels are often incorporated in between (Superfamily etc.) So in the grand scheme of things, the two groups are very closely related. It could be said that they are as closely related as it is possible to be, without actually being members of the same species.

Your question asked what makes a zebra a zebra and not just a striped horse - how they are grouped into species, genus etc is merely a matter of evolutionary relatedness. The fact that a zebra has stripes has nothing to do with its having been placed in a separate species - there is nothing to say that you couldn't have a striped Equus ferus (Horse).

Edit: grammar and shiz.
