Just another example of how evolution selects for/against or doesn't select for/against traits. If onset isn't until your 50s, it's plenty of time to reproduce.

Just another example of how evolution selects for/against or doesn't select for/against traits. If onset isn't until your 50s, it's plenty of time to reproduce. Granted there might be reduced fitness because older people won't be around as much to take care of children, but back during caveman days, very few people probably lived to their 50s.
- mirimir 8y agoHuh. Indeed, searching "autosomal dominant late-onset" does yield quite a few, in various species. Including autosomal dominant Alzheimer disease (ADAD).
- kendallpark 8y agoHuntington's is also in this category. Although there may be anticipation (onset gets earlier after each successive generation).
