Another fascinating fact? The hormone testosterone elongates the vocal cords, which leads to a deeper — and sometimes squeaky — voice during puberty.

“Girls develop more quickly than boys” is an egregious, bald-faced lie the culture promotes in order to victim-blame girls who are victims of rape, and to absolve young men who rape girls and women. Yes, women older than them. Yes, their teachers. It takes two to tango and none of the culture’s pseudoscientific drivel regarding disparities in pubescent development between girls and boys will ever change that.
Mom’s in control – even before you’re born
Researchers have uncovered a way in which information contained in unfertilised eggs influences the development of the fetus and placenta during pregnancy.
The research, performed in mice, indicates that even before conception a mother’s health may influence the health of her fetus.
Epigenetic information is critical for determining which genes are turned on and off in our DNA.
The researchers discovered that some epigenetic ‘marks’ laid down in eggs during their development in the ovaries and after fertilisation are passed onto the fetus and placenta.
The findings suggest that mothers have the genetic tools to control the growth of their offspring during pregnancy by instructing placental development.
