kittens start out lactose tolerant, just like humans, but then often develop lactose intolerance as they age and don’t need to drink their mother’s milk anymore. some cats are more tolerant than others, and for the intolerant ones you can give them lactose free milk (or “cat milk” which is lactose free milk with nutrients for cats)
And then there are people like me, that ate yoghurt and curd for half a year on a nearly daily basis until I developed a tolerance. What a shitty time.
Over time as the lactose becomes a more reliable resource in the gut, bacteria which can process it will begin to grow and with sufficient resources can compete well enough to stabilize in the gut biome. HG Modernism on Youtube has a video on it if you’re interested.
That’s kinda how the very small percentage of humans that aren’t lactose intolerant became lactose tolerant. The only way you can be lactose tolerant, as over 80% of humans are lactose intolerant, is to be defended from mid-northern European ancestry. Basically the proto Germanic and proto Southern Nordic tribes force fed themselves so much cheese and milk that they became lactose tolerant.

You can develop a tolerance to lactose by eating specific foods?? Neat!

Seems like it.

they… stayed the same?
Intolerant ≠ tolerant. They weren’t lactose tolerant originally. We can actually prove that with their remains and DNA.
