Medium Rare

I have an enduring fascination with early man's diet and whether that has altered our current diet to the good  . One thing standing out from these extensive researches is that we are biologically equipped to eat raw meat and fish. which would suggest the following range of cookedness:

• Room temperature
• Seared
• Cooked
• Overcooked
