At 15’ in the air, there aren’t many small animals in front of their faces.

Are you unaware that small animals inhabit the trees where Giraffes feed?

I have always known it as the “Pinky Finger” myself.

That is a very good point and I forgot to consider that the population would heavily skew the average in the humans favour.

Giraffe’s have more risk of additional bones based on your assertion because they tend to, like all grazing herbivores, eat whatever happens to be in front of their faces. Including small animals.

My money is on the Giraffe having the most bones based on that. haha
