The lottery of the origin of life.
The lottery of the origin of life.
All current living beings, past and present, from the whale to bacteria, from dinosaurs to humans, have something in common and it is the structure, a basic structure of genetic code. Of course, each living being has a different combination or its code may have more. or fewer elements, which thus confers unique and particular properties and characteristics to that species.
The question is that all living beings share the basic structure of the genetic code, the simple answer would be because we all descend from a common ancestor as Charles Robert Darwin theorized, that common ancestor is currently called Luca, for the English acronym for last common ancestor. , emerged according to the latest research 4.2 billion years ago, just about 300 million years after the origin of the earth, which is quite surprising, but if you think about it a little, this answer seems a little strange.
There is another option and that is that perhaps life, like the jackpot in the Christmas lottery, only has one possible and exact combination that leads to the basic genetic code, the one that Luca had, in that case other Lucas would have emerged throughout billions of years of the earth's existence, even today we would not be able to differentiate them from the original Luca since they would have the same life lottery number, the same basic combination of genetic code, but this option is also quite strange, since the combinations necessary for life to arise as we know it here on earth or anywhere else are very complex and still full of mysteries.
That experiment where with some test tubes an attempt was made to reproduce the conditions of the primitive earth and that electricity and electrical charges were introduced and that some amino acids and some precursor substances of life were obtained, but according to the authors of this research from the University of Arizona, The current understanding of how the code evolved is flawed, because it is based on misleading laboratory experiments, are terms they put in their statement.
