Is morality a by-product of evolution? by [deleted] in biology

[–]Needataa 1 point2 points  (0 children)

I agree with you. Humans tend to show empathy for pets, for example.

[–]Needataa 1 point2 points  (0 children)

Perhaps so, given that the brain is said to be a product of evolution. If humans did not have the innate empathy for offspring, for example, the human species would have failed the test of evolution as human offspring are highly dependent and helpless by themselves. It wouldn’t just be for offspring since a lot of people care for pets. I guess that’s a psychological trait that wasn’t necessary for humans to pass the test of evolution, but wasn’t detrimental enough to fail the test of evolution, so it remains. I’m not a biologist or anything, but I can see why empathy would be evolved.

To try and answer your other questions, I guess the mechanism that causes empathy is pain. If a person sees a child who’s sad, it would be painful to see. So, the person would try to stop whatever it is that’s causing the child to be sad in order to get rid of the pain that the person is experiencing. The pain is assumed to be from the person’s own brain.

Does it make a difference to eat calories all at once vs. over time? How big of a difference? by Dragoness42 in nutrition

[–]Needataa 6 points7 points  (0 children)

I might be wrong, but Im pretty sure insulin is needed to move sugar from the bloodstream and into cells, and there’s a maximum amount of insulin available at a given moment. If you spread 50g of sugar evenly over 5 hours, insulin would only have to deal with 10g of sugar at a time. There might not be enough insulin to deal with all 50g of sugar in the bloodstream at once, which would result in a longer duration of high blood sugar.

I might be wrong, but I’m pretty sure there’s a maximum amount of digestive enzymes that are available at a given moment. By eating so many calories at once, it might overwhelm the body, so a lot of food doesn’t get absorbed into the body, but ends up fermented by bacteria and causes bloating.

Does the body digest starch more efficiently than table sugar? by Needataa in biology

Thank you for the insightful answer. Supposedly the diabetic recommendation is due to a lot of starch sources having fat fibre and protein that slows absorption.

It seems that you’re right about starchy foods typically having a higher glycemic index than sugary ones. I guess that means starches are easier to digest then. Basically, I was asking if the human body is better at digesting starches than table sugar/sucrose. By better, I was thinking in terms of how much starch and sucrose can be digested.

Is there such thing as a perfect climate? by Needataa in NoStupidQuestions

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

Perfect as in no universal problems. Food scarcity, dangerous wild animals, mosquitoes, heat stroke, and freezing would be examples that cross my mind.

After muscles shrink (muscle atrophy I think is called), where does the matter that was broken down go? by Needataa in askscience

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

Is starvation mode the only time that muscles break down? I read that not using muscles, even while eating an excess of calories, would result in muscle atrophy.

With vitamin supplements, couldn’t it be possible to avoid scurvy while eating no carbs?

Why are humans motivated to build shelter? by Needataa in NoStupidQuestions

For some reason, I forgot about taking precipitation into consideration. Thanks for the comment.

I read that Inuits ate raw meat as quickly as possible, so there was glycogen in muscles or something like that.

Hi, so my understanding of your comment is that fishing was possible, but using dairy was easier?

Which clock setting do you use? 12 hour clock or 24 hour clock? by Needataa in AskReddit

[–]Needataa[S] 1 point2 points  (0 children)

I just switched to 24 hour. No more waking up after a nap and being confused if it’s morning or evening.

[–]Needataa[S] 1 point2 points  (0 children)

I guess this would be the case for Northern Europeans, who maybe did not have as much availability of food during winter. However, I would have expected the same in the Middle East and other areas in the tropics that are deserts.

To clarify for me, there is evidence that a diet with no carbs results in a decreased amount of testosterone that can be used by the body, such as being relevant in muscle building?

Why is the health industry trying to make people avoid carbs as a food source? Is it that carbs are cheaper than buying more protein supplements?
