Why don’t you clarify wtf you mean then? If you are trying to say that evolution might select against rH incompatibility that theory would require the development of some kind of way for people to be less attracted to people with different rH status. Plausible but not sure it could be studied that directly. If you are trying to say that fetuses with rH incompatibility get miscarried (ie we have evolved to miscarry them) because they are less fit (apart from the rH issue) I don’t think that is provable. What the actual issue is, is one of many biological life threatening issues that exist due to the randomness of life, that humans can now fix with technology. If anything suggests something about evolution here, it is that our brains’ ability to solve problems has been selected for because it allows us to fix issues with our offspring so our genes get into the next generation. |
A Rhogham shot is an easy way to avoid a dead baby. I got one for my second kid and it was painless and not particularly expensive as far as I remember. These shots are part of the (many) reasons, infant mortality has declined. And FWIW-my OBGYN did write my blood type incorrectly and I caught it, which was a big deal, because with what she inputted, I wouldn't have needed a Rhogam shot, and my baby would have been at risk. People need to get a basic understanding of biology to be good advocates for their children. |
They shouldn't have kids together. Find another partner. |
For Rh incompatibility, they literally are. |
Here's the point that I've been trying to make. If you know that you're Rh negative then by avoiding having a child with an Rh positive person, you completely eliminate the risk of Rh incompatibility and the need for Rhogam altogether. If you avoid heavily drinking alcohol, then you reduce (but not completely eliminate as it has other causes) your risk of cirrhosis of the liver and the need for a liver transplant. I am all about trying to reduce or eliminate your risk (when possible) BEFORE you get to the point where you need medical intervention. |
PP's got some fan fiction up at AO3. |
And that includes other diseases that have a genetic component too. Also, don't have kids if you are over 35 because of the risk of complications. It's a tough idea for some to come around to but it's better for society. |
| This thread has gone way way off the rails into cuckoo town and totally off OP's original question. |
Sure, but ... we're not without the invention of modern medicine. You know that, right? Other things that are disadventageous to the survival and wellness of offspring, but for which (hooray!) we now can deal with easily: 1. Near-sightedness 2. Allergy to strawberries 3. Propensity to get strep throat 4. Asthma 5. Imperforate hymen 6. Hernias Any of these literally could lead to death in the 1300s. Guess what? They don't have to, and there isn't some magic intentionality we can appease by discouraging people with a propensity to developing strep throat from reproducing. |
hey let me introduce you to the wonders of the standard newborn screen (heel poke) |
Jesus christ, lady, I sure hope you stay home in a box to prevent interacting with the world and never get sick or in any accidents, so that you never ever take antibiotics or go to any emergency room or do anything ever at all, because a Rhogam shot is about as low-risk, cheap, one-and-done as you can imagine. You sound an awful lot like a eugenicist. |
The poster said that's too late and that baby never should have been conceived. |

I am all about trying to reduce or eliminate your risk (when possible) BEFORE you get to the point where you need medical intervention. If there was a definitive way to eliminate or reduce the risk of all of the things that you have listed BEFORE you get to the point where you need medical intervention, then I'd be all for it. Until then, it's like comparing apples to oranges. |
Not an awful lot like a eugenicist. A full blown eugenicist. |
If I have flat feet, should I inspect the feet of the man on the first date, or do I ask before we join up for coffee? Are you insane? This makes sense for something incurable and devastating like Tay-Sachs Disease. It literally makes no difference after birth for someone born to parents who were Rh-incompatible, and at the cost of a single $120 shot. No difference after that. Literally total normal life. You are quite cuckoo clocks. |
