Evolution and Biodiversity as Base of Life

Evolution as we know is the change through time of humans, animals, trees, Earth, etc... There is also a more specific type of evolution known as Biological Evolution. It explains the changes in gene frequency in a population from generations. Also this type of evolution study the descent of species from common ancestors. We will be joining them to understand the process of change (or evolution) through millions of years of history.

Each living organism in the world has an important role in the planet. Each one of the species who populate the planet Earth is in charge of a minimum part of the controls of it. I mean think of it as if Mother Nature, the one who is in charge of everything, gives a single task to every living species so they help to keep the place running as it should be and we can all survive. For this to be possible we need to work together, so if one changes something, the others will adapt to the alterations, changing their characteristics through time. I am not saying the change occur from one day to another, evolution takes a lot of years to be consider as Evolution. Even though, evolution of species never ends, because of the balance we want to obtain. 

Did we evolved because of past actions of our ancestors? When I said ancestors, I am not referring to our grandparents or their grandparents, or the grandparents of those grandparents, I am referring to our ancestors of million of years ago. I will say yes. Evolution is the result of some actions our ancestors has done. Lets say at the beginning the giraffe had a small neck because their food was found in bottom of the trees (leaves). But when trees become taller, because of some changes that make them grow, the leaves where at the top so they had to adapt so they could eat, and with a lot of time so they could change, they finally evolved so they can eat from the top of the trees. You see it is a chain, so because of some action you receive a reaction and so on. The species work together so they can all help each other and maintain the needed balance to succeed, that is called Biodiversity. 

Biodiversity is another important thing to evolve and so that we progress. Why biodiversity is so important? The most important reason is because it helps maintain balance of nature and preserved all living organisms from become extinct. When we see it from a socio-economical point of view it gives shelter, it gives clean drinking water, air, source of medicine and of food, which keeps us alive. 

Nitrogen Cycle can give es an example of what 

Biodiversity means. It shows how the product of 

A is needed to help B, and the product of B 

is needed for C and D, and so on.

As we can see Evolution and Biodiversity are connected and are proportional to each other. If something changes, if there is an alteration in something, all the things that evolve around it will alter and try to adapt to whatever the situation is needed to survive. That is why both of them become the bese of life, because without one of them a lot of species would be extinct today.
