?????? What's even the question?
There are lots:
Biology and Medicine - cloning and expression of human insulin in bacteria (stopped having to produce it from pig pancreases); Watson & Crick discovery of the structure of DNA; gene therapy in humans
Chemistry - determination of the exact number of molecules in a mole (Avagadro's number); discovery of radioactivity (Rutherford); the invention of nylon (DuPont); Boyle's law (behavior of gases)
The outer core is less dense than the B.)inner core. This because there is more pressure on the inner core resulting in a higher density. This increased pressure even makes it solid versus the liquid outer core.
I would assume a population with greater diversity would survive above quantity because of the varying difference in the genetic capabilities.
