This is an excerpt from an email that I received today from Vishen at Mindvalley. If you are unfamiliar with him, do yourself a favor and check him out. He has a lot of knowledge as well as wisdom.
"The Rarest Trait in Nature
Out of more than 5,000 mammal species on Earth, only a handful have evolved menopause.
Humans.
Killer whales.
Pilot whales.
Belugas.
Narwhals.
That’s it.
Now think about this.
Evolution is ruthless.
It eliminates anything that doesn’t serve survival.
So why would it turn off reproduction in a female who still has decades of life ahead?
We assume menopause is a ‘decline’. A biological shutdown.
But it turns out, it’s an upgrade.
Scientists call this the Grandmother Hypothesis.
In certain species, older females become so valuable to survival not by giving birth, but by giving guidance, that evolution rewired their biology on purpose to free them from reproduction.
So they could lead.
Let that sink in.
👉Evolution didn’t make a mistake.
👉It made a decision."
