Eli5—Why is it that we all have different voices? I understand the idea of male and female, but I’m referring to tones. Vocal performance. Range. Etc.
In: Biology
Human bodies are self assembling. There are genetically directed tools that put “all the pieces in the right places”, But there are also a huge number of variables that affect the small details.
Details that were important to get exactly right like the particular proportions of the eyes to manage focusing light are very tightly controlled by extra instructions and processes in our genetic code because they *need to be*. And despite being so critical, those still often times go wrong in many different ways.
However, structures are generally only as precise as evolution required. There are different lengths, thicknesses, stiffness, etc. properties to our vocal cords and the resonating structures we use to create our voices which creates a nearly infinite set of unique sound characteristics because there was no reason in evolution for our bodies to spend extra “effort” to make them be exactly (or more exactly) the same.
