It might be misleading to say they were the first out of Africa. I think there was 100,000 years or so between homo sapiens leaving Africa and arriving in Australia.

Also I think they might have been able to walk due to lower sea levels at the time.

Finally it’s pretty likely that homo sapiens (in this case aboriginals) hunted mega fauna to extinction.

Forgive me, because I’m struggling to understand the linked information, but as someone with atherosclerosis this is an issue close to my heart (ha!).

I just want to make sure I understand you.

Your link to the european heart journal says that the causal link between LDL and ASCVD is “unequivocal”.

I think the WHO study says (amongst a lot of other complicated stuff) that replacing SFAs with PUFAs and MUFAs is more favourable than replacing SFAs with complex carbohydrates? The strong implication being (although I couldn’t see this exactly) that higher SFA intake contributes to heart disease.
