More offspring are born in a population than can survive

Yes. Animals and humans have instincts. Every creature does. Most of the time offspring are born in populations that are thriving so their young and their genes can be passed on.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
