HN title mangling strikes again. “How embryos shape their limbs” and “Embryos shape their limbs” are completely different titles for a discovery.

Why do people do that? I've been on HN a while and have never figured how changing "How x" to "x" helps anything or complies with any guidelines or anything like that. The guidelines have an example specifically leaving a how in there:

>we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X,"

Any ideas?

It's automatic. If you post and the title gets mangled you can go back and edit the title and it won't get re-mangled, but you kinda have to be paying attention and be aware of that.

How is it different to the first line of the article? "Canadian scientists have made a significant advance in understanding the mechanisms that enable embryos to properly form their limbs"

Because the discovery is how, not whether.

The mangled title removes the sense of a qualifier.

They've found some real chemical P and S for the turing patterns
