To whoever asked what was a human some weeks ago!!

It’s literally 1am a half and this popped into my mind, someone asked what was a human or what makes us human idk, i remember answering with an answer inclined more emotionally speaking, but i remember the biological answer, it’s the number of chromosomes per cell, each species has a precise number of chromosomes that codes every single feature in our body, so what makes us biologically human is having 23 chromosomes pairs, there are exceptions of course like people with Down syndrome who have a third chromosome in their 21st pair, I pray this reaches you!
