Amolecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 5 million years. how many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of eight mutations?
answer
1.5 million years
10 million years
20 million years
40 million years

"40 million years" ago did the two species share a common ancestor if the molecules found in these two species differ by a total of eight mutations. The correct option among all the options that are given in the question is the fourth option or the last option. I hope that this is the answer that has come to your help.

Mass can't be changed, It is not variable so it will stay the same in any condition. Texture on the other hand is variable it will change under the pressure or the atmosphere.
