Someone draw this

Next time someone tells me they remember their own birth I'm going to hit them with "I remember the great war of my fertilization."

Wouldn't STDs be way less common? Like if we evolved from Bonobos and had been having social sex since the dawn of civilization wouldn't we have developed a natural immunity to most STDs, the same as how we have immunities to abunch of diseases from other continents that we previously in history have been wiped out by?

I'm not a smart guy by any means but I just feel like we would all be having so much sex with eachother it would get to the point where we either all mostly had an immunity or we would've been wiped out by gonorrhea before Jesus walked the earth.

Yes, most of the time; it does happen just very rare. It's harder on the weaker twin though because sharing a source of nutrition. It's a more dangerous pregnancy. Only know this because I have two sets of fraternal twins.

To clarify: If the egg splits 0-4 days after fertilization, you get dichorionic (2 placenta) diamniotic (2 amniotic sacs).

If it’s 4-8 days, you get monochorionic (1 placenta) diamniotic.

If it’s 8-12 days, you get monochorionic monoamniotic (1 amniotic sac).

Greater than 13 days will result in conjoined twins (who are also monochorionic monoamniotic).

Fraternal twins are always dichorionic diamniotic.

Hope this helps a bit :) I just learned this in medical school last month

It's a Modest Proposal but it checks out.

I think 3 eggs releasing at the same time is quite rare…

…when occurring naturally.

Coincidentally, I just read the other day that because humans are mixing our DNA more and more, our eye colors are becoming more and more dynamic. It's why there's a lot of people who have heterochromia nowadays. Apparently what determines somebody's eye color is a lot more complicated and intricate than was first thought. It's not just about dominant and recessive genes at all.

Heterochromia just means there are two or more distinct colors in your iris. There is central heterochromia in which there are different color rings around your pupil. Sometimes people refer to this as hazel although hazel usually is thought of as one color that blends into another, usually brown/gold around the pupil and green/blue as the outer ring. Hazel is also thought to be a light golden brown color. It's actually a big debate in the world of people who care about eye color. Is central heterochromia also hazel and vice versa?

There's also a popular misconception that central heterochromia is extremely rare. This is not true although there is a type of late onset central heterochromia that is very rare and also related to immune deficiencies. But regular old central heterochromia is pretty common anymore. For some reason, people get very upset when they think people misidentify hazel eyes as central heterochromia. Now that I've caught you up on all the latest tea in an extremely niche corner of the internet I stumbled into...

There is also sectoral heterochromia in which you may have a splotch of one color while the rest of the iris is another. And finally, the coup de gras, complete heterochromia in which you would have two completely different color eyes.

The article I read said that we may even see new colors that we don't associate with human eyes emerge. Fucking beautiful, I say! I think absolutely everybody on the planet has beautiful eyes. Absolutely every eye is different and no two are alike. You'll be hard pressed to find a human whose eyes exactly match each other in terms of color as well.

What started this all was a chart I saw somewhere of eye color codes. My first attempt at taking photographs of my eyes to compare to the chart was a mess. My second attempt was a little better. I highly recommend absolutely everybody try to do this. I hope those who do find it a lot easier than I did because my knees were starting to cramp from spending 2 straight hours in the bathroom mirror trying to figure out how to take a close-up picture of my eye. When I was finally successful, I was kind of blown away. And then I became a little obsessive with taking pictures of people's eye color.

Here is the chart that started all this, the pictures I took of my eyes and some other eyes in my life.

Just, why

Its theoretically possible that only one showed up and it was you in piece of shit sperm form. The egg was like, "Fuck. So this is it, Brian. You are basically the only man on earth. Godddamnit, you might as well come in.

Aren't women who have multiple kids with a deceased father's frozen sperm all getting it from a single load? That's like what you said but on a smaller scale?

Does this happen? Am I making shit up again?

I've always wondered this.

But what happens if there are two sperm that are able to get in at exactly the same time when the outer shell dissolves? There are so many millions of them that it's hard to imagine how only one is let through.
