Our biology teacher once declared a fun, chatty class, and we had fun, but forgot to take notes! She spoke about all the visible genetic aptitudes & differences - you know; haemophilia, being able to curl your tongue, taste the bitterness of cucumbers, having different earlobe shapes, inherited eye-colours etc. At a reunion, we wished we'd remembered all of those she'd mentioned. Does anybody know anything more, or have more details or links about those attributes? Also - we're pretty sure that anyone can waggle one eyebrow, or ear, if they practice for some time - that's not an inherited ability, is it? Thanks for any info! Only curious : )

Stick your thumb up in a hitch-hiker move. If it stays straight up or if you can bend it back at the first knuckle, that's determined by your genes. The widow's peak hairline vs. straight hairline is another.

Okay, so not an ability: but digital hair on your first knuckle of your hand is inherited, and only a very small % of people have hair on that funky knuckle.
