The somatic mutation theory (SMT) is being called into question. After 60 years it has failed to elucidate the specific mutations allegedly required to induce tumour development and cancer progression and fails to explain the vast majority of hallmarks as defined by Hanahan and Weinberg in their 'next generation' update: '...despite 65 years of research on the mutation theory, there is still no proof for even one set of mutations that is able to convert a normal cell to a cancer cell.' https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6115917/ '‘...mutations are increasingly being questioned as the causal event in the origin of the vast majority of cancers …

First of all, I couldn't find much after a quick research but if there is any articles about this topic I want to know. It might be a nonsensical question but how do scientists know if a fossil is deformed or not? I mean, if there is more than one fossil of that species, its understandable. But how do they decide if the fossil is a new species or just a major mutation of another existing species? And is there any chance of, for example, identifying a human species wrong because of a mutated skull? (I hope this isn't hard to understand because of my english)

Hello, I have a question about evolution regarding humans, dinosaurs, and birds. First of all please excuse my ignorance, I thought id come to a forum to get a more interactive answer to this. I fully believe in evolution and am an atheist, but something I cant get my head around is tracing life back to dinosaurs. For example, evolutionary biologists figured out that all birds trace back to dinosaurs, and are in fact dinosaurs. But arent we related to birds and all other species? And therefore should also be related to dinosaurs? But also I remember hearing for a long time that dinosaurs became extinct. Many believing it was an asteroid that wiped…

Hello everyone, I'm trying to time digestion but I don't know how to do it(it's for a school project)... I thought to measure the glycemia rate (blood sugar level) : -Before the meal : get the initial value -After the meal : the rate increases because of the new nutrients -Test every 20min to see when it decreases By this way, I would be able to know how long the digestion process takes for a specific type X of food... So, I would know if my protocol is good and what else I can do to time my digestion. I'm open to any thoughts and ideas... Thank you !

Hi guys, not entirely sure if this is the correct subforum but here goes - I'm writing a uni essay on whether insects should be afforded more welfare in research, and just struggling to find any sources on current conditions or practices, especially any that aren't politically motivated (not saying i'm for or against that, just not what i'm after). Can find plenty on edible insect welfare but not much, if anything, on insects in scientific research. If anyone knows any sources or where to look that would be much appreciated. Thanks in advance.

Hi everybody, I come here often but don't really post much but I listened/watched this video just now and the presenter says that sweating releases toxins from the body. Was just wondering is this true? If so, what sort of toxins are excreted from the body due to sweating? And could this be the reason why so many people choose to do infrared saunas nowadays? Any feedback/insight about sweating and the release of toxins would be highly appreciated Thanks!!

In recent years the discovery of the Bucky ball, C60 molecule, was touted as proof of the versatile nature of the Carbon bond and an example of why it was so good at being the scaffolding of life. But another element can make Bucky ball type molecules, Boron. The B80 molecule is stable and shows that Boron is also a very versatile atom, does this point to the possibility that Boron might in some environments make a suitable scaffolding for life as well? commercial advertising links removed by moderator

Hi. People with historic generations living at high altitudes capture more oxygen in their red blood cells. Would a transfusion to a person without that extra affinity be transferred, at least temporarily ? Has it ever been tried to patients with deficient lung oxygenation ?

Im asking this question to increase my understanding on how evolution works. So if we were able to stop aging and live for a very long time, would I eventually evolve into a different species, or does this only happen when you keep having new individuals over and over?

I'm wondering of there is an explanation in evolutionary psychology (or some other field of science) to the curious phenomenon that red hair in men is regarded as unattractive while in women it is neutral or attractive. Seems to me, from an evolutionary psychology perspective, however it is regarded, so it should be regarded in both sexes, because both have an equal chance of passing the trait on and whatever fitness effect it has it should be equal in both sexes.
