How did early humans modified wild plants they found in the jungle or whatever into the farm crops we see today like corns, wheat, carrots and potatoes?

In: Biology

They selectively bred them. So they took the ones they liked and planted them close together or hand-fertilized them, and kept doing that for dozens, hundreds, thousands of years, and behold: corn that doesn’t look like wheat, edible watermelons, carrots that are all orange (although that was kind of a Dutch thing), etc.

They kept the seeds from the best crops and planted those next year. Repeat for thousands of years, and you have today’s fruit and vegetables

They did the same with animals. Mate the ones with the most desired traits (and often times kill the ones that did not have those traits)

By taking some of the biggest fruits, or tastiest and planting the seeds and growing those plants and then planting the seeds of the biggest, tastiest crop over and over again, eventually the crops got better.

It’s a process called artificial selection, as opposed to natural selection.

Well, the first thing anyone would have had to do to discover farming would be noticing that if you put a seed or tuber in the soil, it will eventually turn into a plant. After that discovery, people would be able to collect the best seeds and fruit they found and plant them. This would then create a crop of that plant. Of that crop, they’d select the seeds of the best plants and put them in the ground again. Then, the next crop would all be the offspring of the best plants. You take the seeds of the best of this crop and plant those. Over thousands of years, evolution would see these first plants become the crops we know today.

For an example, lets take wheat. At first, these would just have been grasses. People would break up the seeds and eat them, and eventually discover things like bread. If, each crop, the farmers select the wheat grasses with the highest number of seeds and largest seeds and only replanted those ones, then over the years every crop would have progressively more and bigger seeds.
