Verterbrate development is a complicated business. Many structures, such as limbs, form as left-right pairs. Of another organs - such as those of the digestive system, which form by budding of the central gut tube - there is only one. And a few organs, most notable the heart, have a much more complicated genesis. The heart's origins can be traced back to the early embryo, specifically to two patches of tissue (primordia) located on either side of the vertical axis that marks the embryo's centre. During development, the heart primordia move towards this so-called dorsal midline and merge, forming the heart. How the primordia find each other has been one of life's mysteries.

Developmental biology: Bringing two hearts together

I think there is a force that exists between the two primordia. There must be something in their chemical composition (or whatever they call it) that exists and helps them find one another coz right now, it's just so stupid to believe that it happened because of 'destiny', and in my opinion, destiny, in the scientific concept is a highly disregardible word!

I want to be a woman of science and live to contribute for its advancements. And love, along with its numerous mysterious ways, has no room for it. Let's leave eros love aside, and focus on being passionate with science. In short, dapat tapusin ko na outline ko before MONDAY!haha:P
