So if it's human (defined as characteristics of human) then that means blood cells are humans too (point 1)? Since it is relating to human, or wait, is it? In embryo stage, most animals' embryos are similar to each other to an extent. Can you truely define if that's a cheetah embryo, or human embryo?

Consisting of humans (point 2). Does the embryo consist of humans? Hmm.... I guess I don't need to explain that (not, it doesn't).

Having human form or attributes... (point 3). Definitely not. At least, not at this stage of the game.
