Arguments for * All life on Earth shares common ancestor
*All life on Earth shares common ancestor
#All life on Earth shares molecular features.
##Same macromolecules (DNA, RNA, protein)
##Same monomers for those macromolecules (five nucleotides, twenty standard amino acids)
##Same chirality of molecules. DNA in all complex life forms is right-handed, research suggests[http://query.nytimes.com/gst/fullpage.html?sec=health&res=9802E1DB1F3DF936A15751C0A9659C8B63] that left-handed DNA would work just as well.
###If life forms did not have common ancestors we would expect to see a fairly even distribution of left and right handed DNA.
##Genetic system:
##*Ribosome structure
##*tRNA structure
##*The universal genetic code (and slight deviations from it)
##*Information encoded in nucleotide polymers (DNA or RNA).
#Differences between organisms can be explained by known mechanisms of genetic mutation.
#*'''Counter:''' There has not been enough time for mutation to generate existing biological diversity.
#**'''Counter:''' There has been enough time enough time to generate existing biological diversity.
#*#The speed of evolution is measured by the [[w:Darwin (unit)|darwin]] (change in an organism's character by a factor of e per million years.) [http://www.talkorigins.org/faqs/comdesc/section5.html#morphological_rates]
#*#Evolution in the lab can be as high as 200,000 darwins.
#*#As measured by the fossil record, the average evolutionary rate in the wild is 370 darwins.
#*#A rate of 400 darwins is capable of turning a mouse into an elephant in just 10,000 years.
#*No other (non-human) process has been observed to generate biological diversity.
#*Extensive biological diversity existed before humans had the ability to create new forms by molecular recombination.
