And if something is 80%/20%, how could it have traces of 3 other things? After all, 80+20=100. Traces other than that would have it at over 100%.
The traces are about a few genes who are normally only found in the other species... since DNA is made of million of genes, maybe you was more pleased if i have wrote something like : 79.99999999999999999999999999999999999999999999999999999999999999999999999% and 19.99999999999999999999999999999999999999999999999999999999999999999999999% ...
Unless, of course, you are suggesting that the Platypus is a miracle from God to show us His greatness by creating a creature that is outside the possibility of reality?
What have God to make with evolution, genetic and science... the Platypus is simply a anomalie, a interesting case...
Is reaction possible without action?
Chemical reactions can be spontaneous, requiring no input... your example is a bad one because you see only one definition of reaction, these who mean "response to another event"...
Is good possible without evil, or visa versa?
No - to both. If God could have done it, then why not? Is God evil? Or good? Or simply indifferent. !?
What is good, what is evil... again something who cannot be define... what is evil for someone can be can for someone other... and again, what god have to make with this...
These topic is about a science-fiction serie... and science have nothing to make with religion or phylosophie... now, i begin to understand why some pepole think that a serie like supernatural is science-fiction...
Is DNA reliant on a carbon based life form? And, how would you know without non-carbon based life forms to compare it with?
don't need to have a life forms for compare... it is simply a chimical fact... the more possible alternative is silicium... around 10 time more rare that carbon in the universe... and silicium is not really a good candidat at the chimical level... main reason why here on earth, with more silicium that carbon, carbon based life is only found... in fact, we are really lucky that the condition on earth have allow the creation of life...
And DNA is mothing more that the building schema for a organisme... so, it is very possible that a alien race use other method for store their "building schema"... in fact, if earth was not protected by a strong magnetic field, DNA will be a very bad choice since high energy particule from space and the sun will be able to break it down...
