An analysis of the history and origin of mars and the possible existence of martian life

Screenwriters have come up with some pretty interesting behaviors for their extraterrestrials, but they often ignore some basic principles of biology. This has long bothered biologist Jack Cohen.

A habitable environment

Alien is not concerned with the biology. But it works as a film, because you see the thing coming out of the chest Another classic horror image of extraterrestrials shows them as giant insects—the alien of choice for the film Starship Troopers —but according to the laws of physics, this kind of anatomy is impossible.

You have to redesign. By far, most films, even the ones with huge special effects budgets, depict aliens that actually look like they evolved on Earth because they have faces that resemble ours.

Nearly all the vertebrates we see around us, humans included, have faces with two eyes, two nostrils, and a mouth below. This configuration came from a common ancestor who lived hundreds of millions of years ago. They must have developed on Earth.

We expect a living thing, a dog or a cat or even a fish, to have a face. Therefore, when we invent something for a film, we give it a face. And that really enables the people who are watching to get moved by it. What are we talking about? UFO sightings and abductions that show up in tabloids?

I think they have traveled to this planet. They might have been here years ago, but they became extinct just like the dinosaur did.

And of course, some people are just plumb crazy! But is it crazy to believe that somewhere, beyond our planet, life has taken root? One of the believers is Frank Drake. I first believed there was life beyond Earth when I was eight years old, not for any good reason, only because my father told me there were other planets something like the Earth out there.

And to my young mind that meant places just like where I lived, with houses and streets and, in fact, creatures that look just like me, which was certainly wrong.

Everything from Duke Ellington to I Love Lucy to the speeches of world leaders is, thanks to our ingenuity, now traveling across space at the speed of light.

Drake reasoned that if aliens were transmitting radio signals of their own, we might be able to detect them. For decades, SETI astronomers have been scanning the stars of the Milky Way Galaxy, searching for signs of advanced alien civilizations."The consideration of possible biotic scenarios for the origin of the ovoid structure in into the evolution of life on Mars.

This seems sort of cyclical. I was living in Oakland and Berkeley when the Bay Area meetups got started, and for a while — until late in or thereabouts, I think — there was a pretty good chance that you’d run into some of the community’s leading lights if you went to the Berkeley meetup.

Traveller type "A" Free Trader Beowulf, mesh model by JayThurman (Cyberia23); This section is basically a rough outline of Rick Robinson's Interstellar Trade: A'd probably be better off reading the full article but some people want executive summaries. The question of Martian life is an age-old one.

There are many theories on the history of Mars, and its inhabitants, or lack thereof. The history and origin of Mars is widely debated, mostly between evolutionists and creationists, though the debate is mainly focused on the origin of the Uni.

ALH Origins and History. Early Mars, and Possible Life: But, if Mars had a bar atmosphere rich in CO 2 which allowed the existence of liquid water and the possible existence of life, what happened to it? Some % of this atmospheric CO 2 would have to be removed somehow.
