Our ancient primate ancestors mostly had twins — humans don't, for a good evolutionary reason

Moral of the story: Big animals have smaller litters?

[Cletus.D.Yokel]

How nice.
But what about those of us who don’t have “ancient primate ancestors”?

[higgmeister]

What is the primate that is between the silhouettes of the bear and the shrew?

[Tell It Right]

Me: Well I'll be a monkey's uncle.

Darwinist: You've got that backwards.

Democrats: This is how we know eugenics is the way to go.

Me: If natural selection works, then why do you have to play God on who makes babies and who doesn't?

“ontogeny recapitulates phylogeny”?...................

[BenLurkin]

Good news. Have all the twins you want!

-
An ancient space alien. They died out long ago. The left us with mysterious megalithic stone structures that modern humans cannot build. Ancient Alien theorists say, “Yes”.

Making up explanatory stories after the fact is not science, it is "just so" storytelling without testability to confirm/debunk the (historical, not scientific) hypothesis. That said, there's no basis for even imagining that natural selection would allow for the existence of sexual reproduction in the first place. Quite apart from the impossibilities of an evolutionary process going from asexual to sexual reproduction, sexual reproduction eliminates half of all contributing parental genes by chance rather than a selection process. In other words natural selection is diluted by half by shifting to sexual reproduction. It is such a marvelous form of magic in the eyes of religious believers (for almost all world religions rely vitally on evolutionary beliefs - the only exception of note is monotheism) - natural selection is able to work constructive miracles here, there and everywhere, and then gets thrown out the window as an driving mechanism the next moment.

You a lizard?

[Red Badger]

I hate it when that happens.................

[Cletus.D.Yokel]

Nope.
Just someone who hasn’t rejected God for some fanciful human train of thought.

The science is in tension.

[algore]

Very interesting.

Women who are in their 30s are more likely to have twins

Women who take fertility drugs are more likely to have twins

Twin rates are about 3%

Many twins are premature and have to spend time in neonatal care.

If only I had a nickel for every time I have said this very thing to my husband...

[wardaddy]

Bears have bumps in litter count after population declines from weather etc too

[SuperLuminal]

Yeah... Sure...
Also, the 2020 election was squeaky clean and honest...

Elvis Presley had a twin brother who died shortly after birth.

I had a first cousin once removed who was a twin--her twin sister died at birth but she lived to 96. Their mother was 30 when they were born.

My grandmother and her brother were twins--their mother was 26 when they were born. I have a second cousin who had twins when she was 26. One of them is the father of twins who were born when their mother was 30. My other grandmother had younger sisters who were twins, born when their mother was 34.
