They should have used this image of Charles Darwin if they wanted to portray an accurate matchup:


Darwin is 51 in that photo. Lincoln was 52 when he took the office of the Presidency.

I'm not sure who would come out on top in a fight between Darwin and Lincoln. Both weren't exactly known for sedentary lifestyles. Lincoln's wiry but Darwin looks tougher. Lincoln has Mary Todd to back him up, Darwin controls an army of wild monkeys.. Yeah, that's it. Lincoln and Todd easily beats Darwin and wild monkey army.
