Becoming humans

BECOMING HUMAN…


I am delighted with the becoming human’s documentary, it’s a really good one and I have enjoyed a lot with all the theories that they explain about the human’s ancestors.

From my point of view, the more information we have about our past, the most prepared we are for the future.

To know about when and where the human’s life begins it’s an important fact, but nowadays we’ve got a very little clear information, and I think that the most interesting is coming!
-I would (...) stand out the discovery of Lucy’s skeleton.


Lucy had a small brain and was only about one meter tall, the pelvis showed it had been a female, and the team named her Lucy after the Beatles' song "Lucy in the Sky with Diamonds." I couldn’t imagine the happiness that his discoverer felt at that moment!

Another important point explained at the documentary it’s the moment of Bipedalism. In 1978, Mary Leakey discovered ancient footprints preserved in the ground around what was once a water hole at Laetoli, Tanzania. These prints showed clearly that small primates walked on two feet there. This put upright walking even further back in time.
But the most important discovered for me is the aptitude to be conscious, what is the same, the “consciousness”.

Sometimes I wonder: Are human beings alone conscious, or are other creatures also conscious? Is an animal such as a dog, for example, conscious?

Yesterday, IN class and with the explanation that we received we could learns that chimpanzees and gorillas may not be able to speak as we do, but this is not because they lack something in their brains; they lack a voice. They have no larynx, or voice-box, and cannot move their tongues as freely as we can.

For one reason or another, human beings evolved slightly differently. We have a well-developed voice-box, and after the first year of life the tongue frees up, permitting the complex sounds necessary for speech. With these two advances, everything changed.

This kind of art representations approach us to our ancestors and to know more about how they feel, how they think…


In short, I think that human(NO S) evolution IS an interesting topic that affect us directly and that MAKES us to pay attention and to be aware of the new discoveries.
