My favorite flavor is vanilla bean, with some chocolate syrup on top. In case you were wondering.
It’s called being in the Goldielock’s zone. Real scientific, huh?
This might be a good place to post this. I wanted to get your scientific opinion on several questions (assuming you’re willing to make a few educated guesses).
We know very little about the physical composition of other solar systems. Given your understanding of physics and pre-biotic chemistry I was wondering the following things.
-
is it reasonable to assume that amino acids and ribonucleic acids are ubiquitous (to some degree) through different solar systems, and on different planets, orbiting different stars?
-
would you imagine that certain features of evolution on our planet would be absolutely necessary for life on other planets? Ribosomes being one of those features, for example?
-
is DNA the only source of biological coding and replication that exists in biochemical systems? Or is it possible that other exist? Has that avenue been run down?
-
if, as I inquire, ribosomes and DNA are absolutely required of a biological encoding and replicating “machine” (as it were) would it also be the case that plant life and animal life are similar features on other planets?
-
what are the degrees to which evolution on another planet would take a drastically different trajectory than our own? What degrees would ensure they follow one similar to ours?
-
last and least, a layman’s question. How vital is the 23.5 degree tilt of the earth to how evolution has occurred on our planet? It gives rise to the seasons, for example. Is it the case that on an earth like planet without seasons, life would look much, much different?
Thank you in advance.
Edit:
- if dna and proteins are possibilities on other planets, are ribosomes eventualities in the gran scheme of things? We know they are possible here. Is it only a matter of time on any suitable planet that a ribosome, for example, would come into being?
Hi Ratspit.
I don’t know if this helps, but scientists have created part of the process of replicating RNA in the lab.
See below:
I thought this may be of interest.
Thank you. Very interesting.
