Your mom's egg and your dad's sperm both contain half of the DNA it takes to make a person, including the DNA instructions it takes to run a living cell. Other cells have a whole copy.

Before that, those cells (egg and sperm) are supported by the body they come from, and their half copy of the DNA only has limited instructions for "running" the cell.

When the egg is "fertilized", the two half copiesf the DNA combine, finding their other half of the code, matching up, and arranging themselves into functional "genes". These genes contain instructions for just about everything; stuff that makes you related to your parents like hair color, etc, but also all the instructions for starting a human from that one cell.

There are instructions for cell division: how many, how fast, how much? .... Instructions for cell differentiation: how many of which kind of cell, where? Instructions on how cells arrange themselves: form a tube, or a ball, fold it in inward, you build this tissue, you build that tissue, you make heart muscle, you make a spinal cord, grow a spine with a tail, but then stop and re-absorb most of it!

After a while, you have a developing fetus that grows into a baby, if things go right.

So their mom.

Things didn't work out well for him (the unnamed soldier), he should have used a stick.

You mean fertilization? Egg and sperm cells are unique in that they carry half genomes, which conveniently make a whole one again when you put the two together. The sperm in this case contributes pretty much just that genetic information to make the egg complete.

The egg then goes on to multiply, and is therefore the common ancestor of every single cell that will ever be a part of you -- and your own descendants, if any.

Sperm fertilizes the egg and then it keeps dividing into more cells. Wait 9 months and you were born.

But we want cheap Ethiopian coffee, if we stop giving the Ethiopians our food production surplus then they might cut down the coffee plantations and grow their own food. You would then end up with expensive coffee and angry local farmers who can not sell their food to the aid programs.

Your first living cell came from the fusion of two gametes from mom and dad, otherwise known as a sperm and an egg cell. Those two cells each contain one half of the DNA required to make a functioning cell, so when they fuse together to make a single cell, that cell has a full set of DNA it can read to make more copies of itself.

If your asking where the first living cell ever came from? No one has a capital T True answer because we haven't been able to recreate the event in a lab, instead we have some solid hypothesis based on stuff we have seen. The first hypothesis believes kind of three main things: #1 is that the first cell probably didn't look anything like our cells, because it would have been super simple. #2 it probably didn't actually use DNA, and instead might ve used a similar molecule called RNA, which naturally likes to fold in on itself, protecting it from being damaged by the environment, but still acting like DNA as a blueprint for cell processes. #3 is that the cell would have come about randomly in the sea of primordial soup after many many many many many years of random chemical reactions. Eventually the right sequence was hit, starting a reaction that didn't just reach the end and stop, but instead caused more reactions to occur and store energy to restart the process again.

That's SUPER high level, barely scratching the surface, barely covering any of the complex things that would have needed to happen to keep those chains going for #3, but hopefully it helps answer your question.

The other hypothesis is something intelligent created the first cells. Where'd that intelligence come from? Ask your leader of choice (priest, rabbi, imam, etc.)

Your mother.

After the egg is fertilised it’s called a zygote and is the first cell that has your unique DNA.

The first cell is a zygote—a fertilized egg. That cell then divides and grows into an embryo, then a fetus.

We do metal machining for the auto parts we make. The parts we make get randomly checked a couple of times per shift for all of the necessary specifications down to a couple hundredths of a millimeter variance.

If a part checks out of spec, the production of those parts are shut down and an engineer comes out to do what is necessary to make good parts again.

While they are doing that, quality control goes to the parts that were made by the out of spec machine and checks them, from oldest produced since the last line check, to the newest produced, until they find where the bad parts started getting made. They are then quarantined and sorted and measured, throwing out all out of spec parts.

They are all virtually identically, only having slight differences of no more than 0.02mm

Yours? Your mom. The egg that was fertilized to make you was a cell.

Well.. now I thought about it.. wasn´t there that roman soldier that not only poked him with a stick, but with a lance, and drew blood?

There´s been one or two, or a thousand pictures painted of it I seem to recall

Edit: Ow, they even gave the dude a nickname

Ha. Stabbed Jesus with a lance? Saint. Obviously.

Thanks. If in a future copy of the Bible there appears a phrase that infers that someone DID poke Jesus with a stick, my job is done.

If you slouch long enough, especially without support, it will hurt.

Good posture involves the muscles of the abdomen and hips to support the spine and hold the torso in an upright position.

When we are slouching, we aren’t engaging those muscles. So, I’m the short term, any t length of your back will start to ache from the strain of sort of hanging between your hips and shoulders.

In the long term, the muscles we should be using become weak and the poor posture causes damage to the spine, causing pain as our bodies rely more and more on the spine itself to hold us upright, when the meat Fram around the spine is supposed to be doing most of the work.

This was covered less than a week ago fwiw.

This right here. We say 'the best posture is your next posture' when working with patients (Physiotherapist here)

No, I believe the tickle test was the primary test for death at the time. While it was pretty good for the technology of the time, it’s nowhere near as accurate as the stick test

literally just spouting hearsay, don't take this as fact -

My understanding is that slouching itself isn't all that bad. The issue is when you don't move around and shift your posture. If you slouch 24/7 it won't be good for you, but if you stand rigid as a plank all the time it won't be great either

& this part isn't even hearsay I'm just guessing, but I would guess it feels good for a similar reason that sugar tastes good. Even though we have an abundance of sugar (or time to slouch) nowadays, it was probably evolutionarily beneficial at one point to be encouraged to relax when possible.

Did you just try to outplay the largest religion on earth...

With a stick?

I like you

Yeah, there used to be lions and leopards all over Europe during the ice ages. They may not have been that far north, though, because there were glaciers covering that far.

We used to have jaguars in Canada overhead in N.America.
