Question

clarify, the distinction between evolution and development..​

Answer 1

There are multiple differences, the most significant being:

Developmental changes can occur at the scale of the individual organism (e.g. a zygote can develop to become an embryo, a child can develop immunity to a virus after exposure or vaccination) while evolutionary change occurs at the scale of a population of living organisms.

Developmental changes can occur within a single generation, while evolutionary changes occur over multiple generations.

Developmental changes occur as a result of something other than a change in genetic composition and are not inheritable while evolutionary changes always occur as the result of inheritable changes to a population’s gene pool.
