Atavism is the rare reappearance, in a modern organism, of a trait from a distant evolutionary ancestor. We describe an apparent case of atavism involving a 59-year-old man with chest pain whose coronary circulation and myocardial architecture resembled those of the reptilian heart. The chest pain was attributed to a coronary steal phenomenon. The patient was discharged from the hospital on a heightened regimen of β-blockers, and his symptoms improved significantly. To our knowledge, this is only the 2nd reported clinical case of a human coronary circulation similar to that of reptiles.

The basic anatomy and physiology of the mammalian heart is very different from that of the reptilian heart.3 Unlike mammals, reptiles have a single ventricle responsible for distributing mixed blood to both the systemic and pulmonary circulations, which are not completely separate from each other. Hence, the reptilian heart has been called the “transitional heart.” In poikilothermic (“cold-blooded”) reptiles, the heart has a unique adaptive value that enables the conservation of energy during prolonged hibernation.

Interesting find Octo and they specifically relate it to a distant reptilian branch of our evolution.

I have no idea. People are born with tails too. Interesting how these things manifest themselves in modern humans. Our genetic memory is impressive.

The shape shifters are here?

I question the general assumption that felines are inherently deficient in the area of grammar and sentence structure.

Now we can all have a tail, if so desired (see vid at link).

I have a cousin with gills behind her ears. Not true gills, just little flaps of skin but she's been told they're not uncommon. Apparently our ears evolved from gills.
