When humans settled in Central America (about 15,000 years ago), they didn't have to domesticate the avocado. Pick these wonderful fruits from the tree and eat. Save the bones and plant wherever you want. No fiddling around raising fruitful varieties from wild ancestors. These are not millennia-long attempts to domesticate corn.

But how did it turn out so well? The fact is that all the breeding work, even before people, was done by someone else, simple, but big. And people came to everything ready.

imageTo understand how this happened, let's observe how natural selection works in plants. To win the competition, they have to come up with clever breeding methods. The task is to spread the seeds over a large area.

If your seeds just fell and rotted under the tree, there is little use. Part of it will certainly germinate, an even smaller part will survive to adulthood. But the population of such trees is at great risk, because the parent is competing with its own children in a small area. You need to spread in all directions and occupy free spaces, then the species will flourish.

imageAlways I wondered how our brain really works. It is interesting to know how our brain really works, and how much we use of it. You will be surprised when you read this.

Today I was sitting at home, my boyfriend came and asked 'what does this remind you of?' and I had multiple thoughts in my head, but answered with one word. How come your brain works so fast and it never stops? Have you tried not thinking? I try all the time but it is impossible. So I really wanted to know how much we use of our brain, and how clever we really can be. So I thought I would do some research and figure out how our brain works. If you are wondering about this, read along, and I will try and make it understandable.
