Did you know: that the a**hole was formed first?
Well. Now you do.
fascinating fact of developmental biology. In humans and other deuterostomes, the first opening that forms in the early, ball-like embryo—known as the blastopore—becomes the anus.
Here are the key details regarding this developmental quirk:
The Process: During gastrulation, a dent forms in the embryo. In deuterostomes (a group that includes humans, sea stars, and vertebrates), this hole becomes the anus, and the mouth develops secondarily.
The Terminology: The blastopore is the very first opening of the gut to develop.
Evolutionary Context: This developmental pathway is shared across many species and dates back around 550 million years to the first worm-like creatures.
Other Views: While the blastopore becomes the anus in deuterostomes, some studies suggest that in certain organisms, the blastopore can elongate and close, potentially giving rise to both the mouth and anus simultaneously.
So, from a purely developmental standpoint, it is accurate to say you started life as an "a*shole" first.
