Quran's scientific miracle in revealing that " the sense of hearing develops before the vision, as well the heart is the first organ to develop and function in the embryo"
Quran's scientific miracle in revealing that " the sense of hearing develops before the vision, as well the heart is the first organ to develop and function in the embryo"
It is He Who gave you hearing, sight and hearts. How little you give thanks! [23:78]
We had assigned them the (faculties of) hearing (ears), seeing (eyes), and hearts [46:26]

On day 10 after fertilization, the human embryo is completely embedded in the uterus wall, by days 15-16 it develops to a "gastrula" a sphere that contains three stem cell layers (germ layers). The Germ layers are arranged one on the top of the other. Ectoderm is the furthest layer from the uterine wall, it differentiates to the brain and nerves. On days 19-21 the "Otic placode", a small neural plate, rises from the brain area and stars differentiating to the auditory neurons and ears. On days 21-22, the Optic placode appears and starts differentiating to the vision neurons and the eye
in the same period, at day 19, two tiny blood vessels "Endocardial tubes" appear in the " Mesoderm", the middle layer of the gastrula, the endocardial tubes grow parallelly till they meet and coalesce to form the heart
In the fourth week, days 22-23 the heart starts beating and pumping the blood, to be the first organ to function in the embryo. Noteworthy, The Human embryo is the only creature among mammals and vertebrae who develops the sense of hearing before
the vision
