Interesting from Eric Vilain here, who works with various sports feds and advocates for inclusion of transowmen in female cats.

“It is not about making everybody biologically equal, and I think that is a common misconception when we start talking about transgender athletes."
“People want transgender [females] to be physiologically identical to [born] females, and if they’re not, it’s unfair.

That is not possible.”
Dr. Vilain referenced the structure of the pelvis and the mass of certain muscle groups as anatomical differences between the male and female body that will always be somewhat different.

But achieving total equality is not the point, Dr. Vilain said.
The purpose of the NCAA’s rules is to, in a sense, shift the transgender female athlete’s muscle mass and physiology away from that of the average male. The goal is to create a pathway to include the transgender athlete, not create total equality.
“Can you turn a man’s body into a woman’s body? The short answer is ‘no,” Vilain said. “I think we need to move past that idea completely.”

Dear @RichardDawkins

While you gently awake, women are being cancelled, deplatformed, sanctioned.

While you gently awake, legislators in Texas are boldly claiming, despite not quite believing, there are six - precisely six - sexes in humans.

People who make laws are using TikTok for their science info.

Your thoughts?
While you gently awake, I am being questioned by my institute about my use of the words ‘male’ and ‘female’.

Apparently, that’s rude.

Homo = same.
Zygote = of the zygote (fertilised egg).

It means that, for a given DNA sequence, you have the same information on both copies of it. As each copy came from a different parent, it means your parents had the same information as each other.
A common cause is related parents.

If you analyse someone’s entire DNA set, you can get a feel for exactly *how closely related* the parents were. The more events where the sequence is the same in both copies = higher degree of relatedness.
For some genetic diseases, you need two ‘bad’ copies of DNA to have the disease. The chances of you having the disease are therefore higher if your parents are related.

A perfect example of the muddled thinking regarding testosterone, advantage and sports categorisation.

‘T means better performance. It’s debatable whether that’s a sports advantage.’

There are two concepts of ‘advantage’ used in the wider discussion. I think of them as Start and Finish Line positions.

This is an excellent analysis of an article typical of the genre seeking to deny the material reality of sex. @lecanardnoir
This photo is key to Andy’s analysis.

“But which of them is male and which is female? They look different with different wing markings, but unless you are a lepidopterist, it is unlikely you know – and if this was a new species no-one would know.”
“So, our knowledge of the sexes of each individual is non-existent. We do however know that one will be male and the other female.”

An important review.

Considering Sex as a Biological Variable in Basic and Clinical Studies: An Endocrine Society Scientific Statement | Endocrine Reviews | Oxford Academic…
All serious scientific agencies are outlining requirements for clear definitions of sex as it pertains to biology studies.

The Endocrine Society is not the first to make such statements, but this is comprehensive.
Many guidelines, including those from the NIH and the European Commission, demand separation of sex from gender (where the latter is irrelevant in all non-human studies).

And demand clarity on both sex and gender.

The number of people displaying an abject lack of knowledge about the history of colonialism in Africa is frankly mind blowing.

Do you not look at maps? Wonder about languages and town names? Read any books by African writers? About economics? About foreign aid?
Never curious about the various secessions or civil wars? The stripping of mineral resources?

I am no expert, not by a long shot, but how on earth do you avoid it?
I’m not arguing that the average person should have in-depth knowledge. I’m asking how anyone can express surprise at older colonial territory maps and not look phenomenally stupid.
