comment What are non-heritable changes to genomes?
The definition above states "from one cell, or organism, to another" @Chris

comment Which (naturally selected) evolutionary process led to the development of egg-laying?
I'm not saying you are completely wrong, I'm saying you've presented an unsupported argument (no evidence from scientific literature) which, in my opinion, is to generalist because of the reason's I've stated above. You need to see the help pages on how to write an answer on Biology SE.

@tryingToGetProgrammingStraight am I right to think you are asking "what is the evolutionary advantage of oviparity?"

comment Which (naturally selected) evolutionary process led to the development of egg-laying?
@Thaina I know there are plenty of oviparous species and many don't incubate an egg. But you've not given any references and made a very sweeping (thus inaccurate) statement "While newborn develop in egg they need less care so parent can go around caring themselves and don't need to carry a burden much." - You also haven't considered that while a viviparous mother can slowly and continuously provide nutrients an oviparous mother must store enough nutrients for the offspring to develop in the egg from day one, probably a larger initial cost, so it's not just an incubation story

Mutations in Cancer cells are heritable @Chris - they pass from one generation of cancer cells to the next, not heritable in the germ-line of the organism but still inherited within lineages of cells.

Really? Less care - most egg laying birds will incubate eggs around the clock.

comment What circumstances allowed humanity to flourish (Where did ALL the humans come from?)
There is a valid question of why do we see diversity and similarity between and within evolutionary lineages within your question

comment What circumstances allowed humanity to flourish (Where did ALL the humans come from?)
I think you should remember that although Twins/triplets etc. are rare in comparison to other species, a mating pair can have more than one brood - the problem you describe only matters if a pair of humans can only produce one child...

Voted to close because as it stands this is too broad and unclear to get a clear answer, will remove the vote if the question is clarified properly

comment Nature Scientific Reports vs. BMC Genomics
Definitely try academics se - I'd also suggest nsr because it sounds like getting to bmc genomic is a safe card now

comment Is the attached digital camera on the top have the same magnification than visible in eyepiece?
not necessarily, I could change the eyepiece to a 5x, or swap to a camera that has a higher magnification built in to it. plus you can enlarge a digital image later (like projecting it to a bigger screen)

comment Is the attached digital camera on the top have the same magnification than visible in eyepiece?
I think it does not, in my set up I can change the eyepiece without it affecting the output image. I don't know if other scopes work in different ways (analogous to an SLR camera)

For what its worth, on the scope I'm using right now I put a ruler underneath and could see 30 mm of it through the eyepiece and only 26 mm on the camera output.

It's also very difficult to answer with out more detail. e.g. It makes an enormous difference regarding magnification if you use a 15 inch computer screen or a projector.

I'd say it's more closely related to physics (seeing as its about the principles of magnification) & technology rather than biology. It's not a biological question.
