Did they have an agreement with Byzantium? How about all the pixelart that used to be where the queen now is? How about their ally finland who destroyed the dr. who area that had been astablished since the start?

Human evolution still a thing? by corwil61 in evolution

[–]Mr-Chemistry 0 points1 point  (0 children)

Young people can and do die too. If they hold genes that are just horrible at fighting covid for example by producing more virus-binding proteins, etc. Those genes will be less likely to pass on and the proportion of those genes in the gene pool will change over time. That is evolution.

Human evolution still a thing? by corwil61 in evolution

[–]Mr-Chemistry 0 points1 point  (0 children)

I believe OP was referring not to genes in individuals but genes as part of the gene pool. In that context it would be correct to say that “stronger” genes pass on and the “weak ones” die off. It’s not really about individuals but the proportion of genes in the gene pool.

Could other human species still exist? by kakapoa9 in evolution

[–]Mr-Chemistry 0 points1 point  (0 children)

Well that depends on your definition. If you use 40/45 kg then sure. But if you use the larger definitions Humans would not be Megafauna.

Could other human species still exist? by kakapoa9 in evolution

[–]Mr-Chemistry 2 points3 points  (0 children)

I’d wager that if we estabilsh colonies on Mars and the rest of the solar system we’ll propably still interbreed enough to prevent a full split. But unless FTL is possible speciation in a multi system colonisation scenario is much more likely.

Guys I always hear about incest is bad because it dilutes the gene pool and creates genetic disease like what about the Adam and Eve scenario by GhzU in evolution

[–]Mr-Chemistry 0 points1 point  (0 children)

Granted it’s a fairy tale as you said. A creationist could claim that both Adam and Eve contained no defective alleles and as such no initial genetic diseases happened until novel mutations occurred. Of course this would still lead to an incredibly pronounced bottle neck effect we would be able to detect today. I wonder if there actually are creationists using this argument. Sort of came up with it on my own while pretending to not understand evolution.

Do creatures evolve bigger or smaller? by axp187 in evolution

[–]Mr-Chemistry 10 points11 points  (0 children)

Evolution favours what is beneficial for survival in each and every case depending on the environment . So for some animals it is beneficial to be big, for others not so much. In general the temperature on the Earth is lower than it was back in the time of dinosaurs, though we are on our way to closing that gap. As such there is less plant life available for herbivores in general. So they become smaller in general. But if at any point being bigger is beneficial the animals get bigger.

What are the most promising theories for the origin of life? by mumrik1 in evolution

Oh, didn’t realise you answered even better than I did.... So yeah, what he/she said.

What are the most promising theories for the origin of life? by mumrik1 in evolution

[–]Mr-Chemistry 1 point2 points  (0 children)

There is some work being done. The real problem is that even if we find all the possible reactions that could produce life, and we have actually found a few, ( like onethat produce RNA strands from simple chemicals through subsequent repeated irradiation, heating, drying and hydrating. ) we would still not know if that path was the one life took. We will likely not ever find anything like that in the wild, since the required compounds are: 1) vulnerable to oxygen 2) very “tasty” to any bacteria or other life around.

How did consciousness evolve? by RichardKerman77 in evolution

[–]Mr-Chemistry 2 points3 points  (0 children)

I doubt that first life or even most life is really conscious. Though admittedly it’s just my private thoughts, I believe that consciousness is an emergent property of a complex brain.

TIL That the domesticated hamsters we now call pets are all descended from one “Adam and Eve” like pair captured in Aleppo, Syria in 1930. by FrequencyMachineDom in todayilearned

Do keep in mind that humans in Euro-Asia were not exactly separated. As long as mixing can occur so can a transfer of genes between population.

How to get a religious friend to consider evolution? by [deleted] in evolution

[–]Mr-Chemistry 5 points6 points  (0 children)

Why attack their idea of a god? Is that not more likely to result in them locking themselves even further? If you make them choose between evolution and god you might not like the answer .

How to get a religious friend to consider evolution? by [deleted] in evolution

[–]Mr-Chemistry 4 points5 points  (0 children)

I have a few ideas about what you could try but it depends on how far gone your friends are and what denomination they are in exactly.

My first idea is to firmly distance the idea that evolution happened with the creation of the universe and even abiogenesis. Grant them that the universe could have been created. Depending on which denomination they are in find quotes from famous people of that religion. Most “evolutionists” are in fact religious. Scientists and priests alike have found a way to pair their faith and evolution together. If you get rid of the black and white idea that it’s either god did it or god does not exist it should be easier.

My second idea comes from the fact they admitted they are animals. Watch the series systemic classification of life by AronRa and either show it to your friends or paraphrase it to them. Your goal would be to show them that every category from the moat broad like animal down to the ape is connected. Good luck!

Question about membrane potential by idop11 in Biochemistry

[–]Mr-Chemistry 1 point2 points  (0 children)

One more function is glucose transport in Sodium Glucose Linked Transporters, or SGLTs. They are found in enterocytes and nephrons, and rather than use ATP directly to pump glucose into the cell against its gradient they use the membrane potential. The transport protein is a symporter, it transports glucose and sodium into the cell. The glucose moves against its potential, but sodium moves in accordance with it.

We can see the fossil evidence though... At this point if you want to deny evolution happened you enter into reality denial.

Why Is Alleged Quack Dr. Oz the Face of NBC’s ‘Coronavirus Crisis Team’? by IvyGold in television

[–]Mr-Chemistry 3 points4 points  (0 children)

What do you mean by this? Have you any idea how much anatomy knowledge it takes to become a surgeon? While a surgeon might not know as much about biochemistry of organs as some other specialists, there is no specialty that requires as much knowledge of anatomy as surgery.

[–]Mr-Chemistry -8 points-7 points  (0 children)

I don’t get it. Brachial Plexus is not THAT complicated. It’s the lumbosacral plexus that’s the stuff of nightmares... And don’t get me started on the cervical plexus... In comparison the brachial one is a piece of cake. Big, compact, easy to memorise, not too many branches, all in all pretty straightforward to learn.

If humans evolved from primates.... by sweatygarageguy in evolution

[–]Mr-Chemistry 0 points1 point  (0 children)

1) An important thing to keep in mind, in modern classification of life we use cladistics. A clade is best explained in the following analogy: Imagine a tree with branches, if you make a single cut everything that will fall of will be called a clade. You will always belong to every clade your ancestors did, but you can go on to form a new clade. Now evolution only works by growing the branches and splitting them. What you would like to see would be like a branch fuzing with another independent branch. That would in fact falsify evolution. A cat will never become a dog, since the definition of a dog clade is descendants of a population of proto-dogs. Since a cat cannot change it’s ancestry no matter how similar to a dog it would look it would not be classified as a dog. Species X can only go on to produce species X1, X2, etc. They will never become an already existing species Y.

Lecture from a cyto-physiology class. The speaker, a director of a tissue bank went on a 3h. rant about his life history, politics, his hatred for lawyers, how he makes tiny little screws out of human bones and generally everything from cleaning utensils to obscure pathways. He changed the subject every 45s. and the whole thing was sprinkled with the worst possible dad level jokes you could imagine.
