People have often been fascinated with the prospect of the existence of extra terrestrial life forms. Such is our interest in aliens that there are those who have dedicated their whole lives to trying to detect and record the slightest of signals from outer space proving that we are not alone in the universe. The questions are many when pondering the possibility of the existence of extra terrestrials. We wonder which galaxy they might come from, whether they would be friendly to the human species or not, what we could learn from them in advanced technology or even about our own selves and our origins. But probably the most prevalent question on our minds is what they would actually look like. Scientists have chimed in on the question and believe they have a relatively good guesstimate as to what physical form they might take. And you would be surprised to learn that aliens might not resemble what the movies have us believe, but there appearance would be much closer to ours. Scientists suggest that there are some key traits an intelligent alien would have to posses like, living on land in order to be able to develop rocket technology; binocular vision to judge distance; eyes near the brain to minimise the time it takes to receive and process signals; at least two legs for mobility and hands with at least three fingers to firmly grip and manipulate tools. Their resemblance to human beings should not be a surprise, as the leading expert on evolution, Richard Dawkins said that the building blocks of biology like protein and DNA could be the same everywhere. ‘It does look as though protein has got some very, very important properties that might have to be universal’, Dawkins has said. If that is the case, then all life across the Cosmos could evolve similarly to Earth’s, eventually creating being that walked and talked like homo sapiens
