Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

Tough luck, this might affect his grandkid, not the kid. Epigenetic imprinting (the semi-permanent kind) is done during oogenesis, which if I am right occurs during pregnancy.
It's also not necessarily a net-gain. There are a bunch of trade-offs to being better able to deal with a lack of food. Specifically, by sacrificing body mass and brain development to conserve energy.
Surviving adverse conditions can mean developing novel evolutionary strategies. But it can also just amount to evolutionary downsizing. Living as a smaller, weaker, stunted version of your predecessors because the runt of the litter needs fewer calories to get by.
Yeah I was about to say. Aren't children from families that suffered famines much more likely to have (and have children that have) digestive problems and food related deficensies?
And heart and respiratory and neurological, etc etc
