A functioning cell has been known to be required       to develop a functioning organism for a very long time. Just putting       DNA into a lipid bubble will not result in a functioning cell and my       guess is that it has never seriously been considered to be possible.       Even the artificial genome developers have to put their genome into a       bacterium that they have removed the DNA out of.              You do not seem to understand how descent with modification, biological       evolution, works. New genetic variants and new combinations of genetic       variants inherited through sexual reproduction all have to work within       what is already working to create the organism from a fertilized egg       cell. It is the way that reproduction has worked since the first cells       evolved a means to make sure an adequate set of genes was transferred       into each daughter cell of mitotic cell division.              Every genetic change has to be able to develop a human being from that       single fertilized egg cell or it is not propagated in the population.       This has been going on for billions of years. Every change has to work       within what is already working. That is how biological evolution works.        Eukaryotes evolved sex and gamete production over a billion years ago       as single celled organisms, and the human egg cell is the result of over       a billion years of change. Every change had to work within what was       already working.              Ron Okimoto              > My deduction is, the ovum contains a large amount of information for the       > development of a "generic" human (i.e. the subsystems listed below*);       > the DNA also (presumably) contains information for the development of a       > generic human, as well as most/all the information for family traits.       >       > This is not an argument from incredulity, rather, the burden of proof       > rests with the claim that 80 MB in DNA is sufficient.
