You literally expect me to go and find journals for you, and the names of scientists and so on, when you can just do all that yourself

sakura184 · 08/07/2019 23:36

Yeah but the blog I linked to references all the scientists in the field, along with their pictures and research history, so if you want to research further yourself using scientific journals etc knock yourself out

WordPress blogs as article sources Grin
Seen it all now.
I have a WordPress blog, anyone can write anything on there.

In 2004, in an article titled, “The Degenerate Y Chromosome – Can Conversion Save It?” Graves responded to Page: “(The discovery of palindromes) will not lead to a drive towards a more functional Y. The forces of evolution have made the Y a genetically-isolated non-recombining entity, vulnerable to genetic drift and selection for favorable new variants sharing the Y with damaging mutations. Perhaps it will even speed up the decline of the Y…”

The Y chromosome has degraded over millions of years. This isn't contested:

Women have about 1.5% more genes than men, — the same difference between women and female chimps, — or men and male chimps. Humans don’t have that many genes to begin with; plants have more genes than humans. An approximate 1.5% difference is major — major enough that it can result in an entirely different species.

I mean it's either true or it isn't. It's not like biology is a grey area is it.

You don't think it's factually correct. That's the funny thing about biological truth and facts though, they remain, and through all the hyperbole they cannot be changed

Endoplasmic you bastard! I need to go to bed too, and now I'm going to spend an hour surfing xkcd. (Just hit random and came up with this gem... xkcd.com/492/).

EndoplasmicReticulum

So you're saying it's not true? I've read this in a variety of sources, not just on a wordpress blog.

Must not get sucked in. Going to bed.

Yup because wordpress blogs are the best place to learn about all sorts of things.

The female X is in possession of about 2,000 genes. The male Y, — once a normal X, has corroded over time into the shriveled lower-case-letter it is today. The Y coming gift-wrapped in the sperm of most any dude you now know has lost about 1,955 genes — ie, over 97% of itself. Currently, the Y chromosome is a trainwreck of about 45 surviving genes. (Some geneticists count 27). These hangin-on-by-their-pinkies-genes are primarily devoted to sperm-making. The rest of the Y chromosome is a wasteland of meaningless repetition. This rate of repetition is between 99.94 – 99.997%. Scientists were shocked by this repetition, and at first, could not distinguish one male from another, — not even from opposite ends of the planet. Sequencing the Y took longer than planned due to the excruciating tedium of this repetition. This repetition is the frantic but failed attempt of the Y at do-it-yourself self-repair.

I read somewhere that the Y chromosome is a mutated X, so men are just women with mistakes! Sounds right to me.

EndoplasmicReticulum · 08/07/2019 22:24

Ah, would have made more sense if I'd read the other thread.

AlwaysComingHome · 08/07/2019 22:17

The thread is because there’s somebody on another thread claiming a Y chromosome is a broken X. I wonder where the other arm goes. Does it just float around the testicles aimlessly?

EndoplasmicReticulum · 08/07/2019 22:05

The first scientist to discover that the Y was the sex-determining chromosome was a woman called Nettie Stevens who studied mealworms.

Is that the sort of thing we're after?
