If I don't meat for a day (12-20h) I get a craving for it.

Probably low on protein.

Maybe cause humans have always been part carnivore? or you just cook really good meat..

It can be one of two simple things. Actual addiction to the taste and texture and such, which will pass with time, or calorie deficiency on days you skip meat, as it is very dense in energy.

However, we adapted to the presence of meat options and therefore passed that adaptation on to our ancestors

Sometimes food cravings are purely psychological. Other times, they are physiological signals of nutritional deficiency. The human body requires the amino acid chains in protein to live, regardless of the source, and it becomes obvious to individuals who are attuned to their bodies. Protein craving hunger is fairly common for males who do moderate to strenuous weight lifting activities, as their bodies require more of it to remain healthy. The automatic, subliminal hunger feedback thing is pretty cool.

Yeah, I have this genetic condition where I have constantly low iron levels. If I go through a couple of days eating iron deficient foods, even while eating meat like chicken, I'll feel light headed and dizzy and just sapped of energy. Red meat does taste more delicious to me than to most other people.

Reasonable, I've had lots of trouble with iron too. Liver and spinach were my lifeblood at one point, still love 'em.

Assuming no allergy, shellfish can help out too.
