The theory
of a land bridge between South America and Africa as an explanation for similar

<span>A </span>land
bridge, in biogeography<span>, is an </span>isthmus<span> or wider land connection between otherwise separate areas, over which
</span>animals<span> <span>and </span></span>plants<span> <span>are able to cross and </span></span>colonize<span> <span>new lands. A land bridge can be created by </span></span>marine regression<span>, in which </span>sea
levels<span> <span>fall, exposing shallow, previously submerged sections of </span></span>continental shelf<span>; or when new land is created by </span>plate tectonics<span>; or occasionally when the sea floor rises due to </span>post-glacial rebound<span> <span>after an </span></span>ice
age.

Culture is defined as C. a learned way of living.
According to the Merriam-Webster dictionary, culture is defined as "<span>the act of developing the intellectual and moral </span>faculties<span> especially by education."
If this is too hard for you to understand, it's basically saying that culture is the development of your intellect and your morals/ethics by education from those people who came before you, previous generations. Culture is passed down from generation to generation, and is also improved/changed.
