If you don’t know who this man is, then, as a Muslim, you owe it to yourself, to learn about him: he is Karl Ernst von Baer. He was a well-renowned German-Embryologist, actually considered one of the founding-fathers of Embryology. Anyway, he did something that’s so important for the World, and especially for the Muslims: he, single-handedly, discovered the functionality & purpose of the Ovum/Fallopian-Egg, by dissecting a Female-Dog. Thus, he came to the conclusion, that not only does the Ovum serve the purpose of facilitating fetal-development within Animals, but in Human fetal-development, as well; but, why is this so important? Because, Allah tells us, within the Qur’an, 14-centuries ago (12-13-centuries prior to even the birth of Karl Ernst von Baer himself) that the Human being was created from Ova/Fallopian-Eggs.(Noble Qur’an: Chpt.96, V.1 & 2) And, ironically, this discovery, single-handedly proved that everything in the Qur’an is the absolute truth, because how could/would it be possible for the Qur’an to be right about something like this, which no one on Earth had any prior knowledge of, and then be wrong about anything else?!!!
