2571>To the best of my knowledge that some types of foregn materials-other than the well known metor or shooting stars- are being deposited contineously on the earth' surface coming from space. I heared that there was at least one Ph. D. Dessirtation was done in England during the 1980s .
Reply:i'm going to say no. dna has evolved in organisms over millions of millions of years on this planet to be just the way it is today. viruses are random strands of this dna or rna (viruses are not alive). the chances that a similar genetic material has developed elsewhere in this universe is extremely thin, and on top of that, there would be a slim chance of it somehow reaching our earth.
Reply:Yes. Tomorrow.
Reply:If this is true it has never been proved. Whilst anything is possible the chances are so incredibly remote that it鈥檚 probably not worth thinking about.
