Choose "innate" if the behavior is an innate behavioral adaptation and "learned" if it is a learned behavioral adaptation.
a chick hatches from an egg.
a. innate
b. learned

Chicks hatching from eggs is an innate behavior. Innate behavioral adaptations are the result of millions of years of evolution. This type of behavior is already "hard-wired" in the nervous system of organisms and is usually inflexible. This is where a certain given stimulus triggers the exact same response over particular organisms through time. The same adaptation goes for other species that are naturally inclined to walk hours after their birth, like giraffes and elephants do. It is in a way nature's natural adaptation for species to survive through the course of time.
