I can think of numerous abilities that I have gained since age (say) 10 and more than a few abilities I had then which I have since lost. In future I will doubtless lose more abilities still. At what point will I have lost enough capabilities to be counted human?
I have an open mind on embryo research, but the inescapable (albeit inconvenient) fact is that an embryo is indeed a human being - if only because it has the key ability to grow into a fully-functioning foetus, and then a baby, a child, an adolescent and finally an adult human - all of them with the same identifiable human DNA. In other words, it is human, alive and an individual.
