Parent and Offspring - Instinct or Environment?

Many traits are inherited from parents. Some traits are not. Some traits are learned.

Do you know a dog that knows how to beg? Did the dog inherit that trait? Or did the dog learn the trait? Dogs learn tricks, like begging, shaking hands or playing dead. Doing tricks is a learned trait, not an inherited trait.

Do you know how to ride a bike? Riding a bicycle is a learned trait, NOT an inherited trait. You were not born knowing how to ride a bike.

Some traits are instinct. Instinct is something that a species does naturally. It is NOT learned. For example, salmon leave the ocean and returns to rivers and swim up them to lay their eggs. They do not learn to do this. They do it naturally.

Some traits occur because of the environment. Environment is the surroundings in which you live. Organisms develop some traits because of their environment.

A 5th grader living in the Andes Mountains of Peru may have a larger lung capacity than a 5th grader living near sea level in southern California.  To adapt to the high altitudes, people living at higher altitudes often have larger lung capacities than those who live at lower altitudes.
