A buddy of mine said people that work out every day going to the Gym and going for runs and being athletic build have stronger heart and lung function.

He said also when they get sick it does not last as long and you coughing way less than someone really fat and extremely out of shape.

Why is that?

What would happen? Serious question, I am dying to know.

It's easy: whenever I eat foods that are too salty, I cough. It doesn't matter if I drink or follow any advice I read online; it always happens.

To be precise, I wanted to test this strange thing and tried to debunk the only explanation I found online that states, "you cough because of your throat's sensitive membrane." So, I tried eating two grains of salt, and it made me cough after 3/4 seconds it touched my tongue. From my experience, I can say that the throat is not involved in this issue.

Also, I'm quite confident in saying that I'm not allergic to salt because I eat it every day, and it doesn't cause me any problems at all, only the cough when it's way too much for a bite.

It was a little under 1 pound of spinach for reference.

So, it is commonly said that reptiles (most of them, anyway) cannot form social bonds/feel love because they do not live in groups so therefore didn’t evolve that ability. But cats, specifically house cats, are commonly accepted to feel love and seem to display affectionate behavior. But cats evolved from the African Wild cat, which is a solitary predator, so why did they evolve to feel love? I know female cats care for their kittens, so maybe that’s why they feel love, but that’s only for a few months, and so do crocodiles. And if that were the reason, why can male cats also feel love if they don’t care for kittens?

Sounds super cut and dry, but I’m curious if a woman today can vomit the whole 9 months, is there any evidence primal women carried worse? A lot of women are also subject to: ges. diabetes, high blood pressure, falling teeth, gum disease, swollen limbs etc. How would this turn out for women thousands of years ago? Why is pregnancy so detrimental to the body now?

Also wondering does other mammals actually experience morning sickness and the whole 9, or is it just us?

I've read that in rare cases these trees will change sex of one of there branches but how common just is this? Better yet, do all Ginkgos have the ability to do this or is this just a rare mutation?

I ask myself this sometimes and truly wonder if other highly intelligent animals like whales,elephants,etc have beliefs? We know orcas,dolphins,etc have different cultures(or just orcas dont remember) so this makes me wonder do they also believe in a being similar to what we think is our god? Do they also think their created for a purpose and that their not animals made from nature?(because people often think we are not animals like the rest for some reason)

I imagine there probably isnt any studies on this, but i just want to hear peoples thoughts and ideas.

It is said that mammals went through an evolutionary bottleneck during the time of the dinosaurs. Most mammals only see two color wavelengths, sometimes one, and sometimes none. This was because our ancestors were mostly nocturnal to avoid competition with dinosaurs during the day. They also have superior smell and hearing than other vertebrates, and fur, because of this.

But why do primates still have good color vision if they didn't diverge from other mammals until 10 million years after the Cretacious-Paleocene extinction?

I have done loud self talk frequently that it has become integrated into my identity. It started since I was a kid because of loneliness and continued to adulthood. I still do that when I am alone and don't even know I am doing it. I sometimes also murmur when speaking with people as a form of processing my thought. Is it problematic and I have been told I am a little slow during conversations (the pace of language is off). What could explain this behavior? Thanks in advance!

OK so this is a bit of an odd one. I recall reading many years ago about a defunct system of taxonomy that assumed that in the end each taxonomic rank would have the same number of "members." It was a particular number, between four and six, so for my example let's use five. According to this taxonomic model, there are expected to be five classes, and within one such class five orders, and within one such order five families, and within one such family five genera, and within one such genus five species. Does anyone know the name of the person who propagated this idea or what the name of the idea is?
Thanks so much!

Hey!

I recently came across the fact that spotted hyenas have really difficult births because of their anatomy, and now I'm curious to learn more about it.

Does anyone know any good resources on this, or would anyone who's familiar with the topic be up for discussing it? I'm also curious if there are other wild animals that have similarly difficult births. Thanks!

Thanks!

If the sound of cracking and popping of joints is caused by air bubbles: how do the air bubbles get in the joint spaces to build up in the first place? Where do the bubbles come from? And where do they go once popped/released out of the joint space?

Imagine GMO single celled algae with more efficient photosynthesis, optimized metabolism, nitrogen fixing and faster growth and reproduction rates. It would cause eutrophication on an unimaginable scale, destroy marine ecosystems and cause climate change.

It would be impossible to fully eradicate.

Even natural algae, aquatic plants and photosynthetic organisms with their inefficiently evolved photosynthesis have caused plenty of cataclysms.

Is this threat real but completely flying under the radar?

We all know that most people have at least one personality trait from each of their parents, sometimes even grandparents or uncles and aunts
But how much if the personality is actually genetic and how do we know it’s not simply the result of growing up around the related people themselves

To make the question clear- if you take a boy away from his parents and raise him with another family, will he still have personality traits from his biological parents and if so is there a pattern of what comes and what occurs coincidentally?
Also I’m only talking about personality and not physical traits

So, I know that lichens are a composite organism of a fungus and an algae, but I was reading Botany in a Day, and it has a chapter on plant evolution in kind of broad strokes. It says that non-vascular plants have partner fungi that help ferry nutrients which makes sense because I know that many if not most plants have partner fungi to exchange nutrients and water with. Where I am stuck is what is the difference between like a clubmoss or a liverwort and a lichen? Neither of them have roots, leaves or stems. They both rely on partner fungi. I may just be misunderstanding what algae, I understand it as a broad group, but that in this case it is a single cell organism that relies on photosynthesis. Is not a plant cell?
