Some Eggs Don't Need Sperm to Make Babies

It's so cute seeing the tardigrade's little mouth parts twitching in the egg.

[@GaleFlamel]

really sucks that the tardigrade hatching footage was obstructed by the ad

[@VoidHalo]

You should do a follow-up about seeds and pollen. I was surprised to learn a seed is actually an embryo. The way some plants reproduce, pollen needs to fertilize the seed, which seems analogous to sperm fertilizing an egg, so I just assumed seeds were the plant analog of an egg. But the fact that it's an embryo is really counterintuitive. Especially when you consider the largest seeds, which are about the size of a football. On a side note, I wonder if the egg cells (ova) from large mammals like whales are any larger than smaller mammals. Would a blue whale ovum be larger than a shrew's?

[@borrero-md1196]

We do basically the same. And although eggs are an amazing example, all cells have an amazing set of "tools" to constatly test and either prevent or promote apoptisis. Imagine human eggs... They can remain in a halted phase of it's cell division cycle for decades (women are born with their eggs already there) enduring all sorts of threats that could and would damage it's DNA and other structures and lay in waiting until it is randomly selected to resume the cycle and maybe be fertilized.

[@binghyong-baebang2236]

How does a single cell creature decide what it should do next? I have seen paramecium run into debris and backup and try again. If it does this several times without success, I've seen them backup, then rotate fast for a short time and then move forward in the new random direction. It kind of looks like a temper tantrum. :) But seriously, what part of the cell has the wherewithal to make the cell spin, then go off in the new direction?

[@maxwellsimon4538]

If I had to guess, each time it bumps into debris, chemicals get released, and one of them signals the cillia to back up and turn. Then if that happens too many times in a row, the concentration of another chemical builds up to tell it to back up more and spin for a longer time.

Spermism didnt even know the egg existed. the oldest trilogy in all of the western canon is the the Orestea. In which the father is the sole source of the son, with no mother being necesarry except as the fertile soil in which the sperm is planted. like a seed planted in soil it is entirely of the seed and nothing of the soil.

[@Vitali_Osandor]

Thankfully, the truth of our (human) species is somewhere in the middle, since both sperm and eggs are necessary for creating life. If only one of them was needed, that would have created further discrimination and inequalities within the human society.

[@mixiekins]

I have a question, when the cell makes those first few divisions, how do they adhere to one another so they don't get separated? Also, if they do get split up, do they continue to divide or is there some way that they can detect that their neighbor went missing? If the latter is true, do they detect that with ambient chemical signals, or is there some sort of signaling through contact of their membranes?

[@Galifay]

I'm not an expert, but from what I've read/watched it's possible for the first few cells that the zygote (fertilized egg) divides into to be separated and still have them develop into mature organisms. Might not be ideal in an egg situation, since the amount of nutrients is limited, but that's how mammals get identical twins - one zygote's first few divisions got separated, and the 2 copies successfully implanted. I actually just learned this by perusing Wikipedia: when the egg begins development of a new organism, it divides until it has 16 copies of itself, and this ball of 16 cells is called a morula ( en.wikipedia.org/wiki/Morula ). Once that occurs, somehow (probably through chemical densities?) they coordinate the creation of an inner hollow space, and the mass becomes known as a blastocyst ( en.wikipedia.org/wiki/Blastocyst ). I would think that identical twins occur when some of the cells during the creation of the morula de-adhere from the main mass, and essentially begin creating *another* morula. But, like I said, I'm no expert. Just very biology-curious.
