You know that little pink thing nestled in the corner of your eye? Its actually the remnant of a third eyelid. In humans, its vestigial, meaning it no longer serves its original purpose. There are several other vestigial structures in the human body, quietly riding along from one of our ancestor species to the next. But why have they stuck around for so long? Dorsa Amir investigates. Lesson by Dorsa Amir, directed by Avi Ofer

Ridiculous, human are human from day one. Our first father Adam was created by the Lord of the worlds.
Its not a trail and error.
For everything theres a purpose, Lord knows the best, human are too small to understand that, we need more Researchers to grab the reason.

falling on tailbone hurt so much, I remember in 9th grade I fell on my tailbone during futbol training and I fell on it, and I wasn't able to play for weeks because it got swollen

Well you say having a tail is harmful to us as we walk the earth instead of climbing among trees, then why so many other mammals have it and why it is not giving them any harm?

this video focuses on darwins theory and as we all know that that theory is completely false I find this video useless + you should have done more research on this
