ELI5: Is intelligence entirely determined in the early stages of life or is it something that can change later on?

Whenever I read about influential scientists and mathematicians, I notice how their upbringings had a similarity: their curiosity and intellects were all nurtured as children. Do people farther down the road of life still have the ability and potential to grow their minds to reach the same heights?

Your genetic code mostly determines how your brain will form and develop, but environmental factors (nutrition, injury, etc) during the growing process play a big part in this. But most healthy brains end up similar to each other in most ways, so barring disabilities, that's not that important.

Most people have the capacity to learn whatever they want, they just need to put effort into learning. Therefore, capability for knowledge is common among people, but actual knowledge is a consciously acquired thing.
