Hint: that was the case in "civilized" places with access to an abundance of introduced diseases, and poor diet dominated by cereal crops. Hunter-gatherer societies were typically healthier, judging by size of skeletons we find.

Of course the Canary Islands were settled by "civilized" people.

Any resources to learn more here? My understanding is the adult sized hunter gatherer remains appear healthy, I’m not sure that is an indicator that more babies made it to that stage

Telling stories and picking berries is very nice but you chose to ignore the fact that majority of your children would die, including a few of your partners from labor, any broken bone would be excruciating pain for life.

No amount of "colonizers bad" is gonna get away from those. Health care has improved tremendously due to technological advances and if you like preventing misery, singing songs and picking berries isn't the way.
