First let me present the article:
The world has been fascinated with the existence of little green (or gray) men ever since the idea of extraterrestrial life first caught the
eyes and ears of the public. Fed by more or less real events, such as UFO sightings, abductions, and inexplicable phenomena such as crop circles,
people's fantasies of aliens have grown over the years, and more so after Hollywood started depicting them in movies. Now, a group of researchers
comes to argue that humans and possible aliens may share the same genetic architecture, on account of the fact that the building blocks of life are
the same in all of the Universe.
According to researchers at the McMaster University in Hamilton, Ontario, Canada, led by astrophysicist Ralph Pudritz, this idea was prompted by the
fact that the way in which amino-acids were found to bond in meteorite samples that were collected from Earth seemed very similar to the way the
building blocks of proteins tied to each other inside all living organisms on our planet. “This may implicate a universal structure of the first
genetic codes anywhere,” Pudritz says, as quoted by Wired.
“Thermodynamics is fundamental. It must hold through all points of the universe. If you can show there are certain frequencies that fall in a
natural way like this, there is an implied universality. It has to be tested, but it seems to make a lot of sense,” he adds. Paul Higgs, also a
biophysicist at the McMaster University, has co-authored the new study detailing the hypothesis, which has been published online on April 6th in
The experts say that the amino-acids required for the formation of proteins are relatively simple in structure, and that a warmer meteorite would
excel in providing the building blocks of life an appropriate environment to grow and to bind in ways that may facilitate the appearance of basic life
forms. And this part of the hypothesis refers to celestial bodies moving around in Cosmos, but similar conditions could be met on a distant exoplanet,
where millions of years of shifting conditions could meet the necessary requirements for alien life to occur at one point.
If it does, because it is based on the same type of construction as we are, the new organisms could also develop the same DNA patterns. It's doubtful
that the entire genetic structure will resemble that found on Earth, but it may be possible that hypothetical researchers could find common ground
between the two types of lifeforms.

Humans and Aliens Might Share DNA Roots
That's the tantalizing implication of a pattern found in the formation of amino acids in meteorites, deep-sea hydrothermal vents, and
simulations of primordial Earth. The pattern appears to follow basic thermodynamic laws, applicable throughout the known universe..Please visit the link provided for the complete story.
My rudimentary understanding of what they are suggesting is that "life" as we understand it can only manifest itself genetically through a single
process. Thus if any alien life were to exist it would have to have emerged the same way life did on earth.
Please correct me on this point if I am misreading it as I am admittedly scientifically challenged.
Of course they are not talking about "intelligent" life, though I do find the use of the term "Alien" rather interesting.
It is not often that one sees in scientific circles the use of the word "alien" without going through an inordinate quantity of qualifiers to make
sure they are clear that they don't mean "little green men."
Anywhoos, just thought I would share these articles with you.
