"In analyzing the COI of 100,000 species, Stoeckle and Thaler arrived at the conclusion that most animals appeared simultaneously. They found that the neutral mutation across species were not as varied as expected. Neutral mutation refers to the slight DNA changes that occur across generations. They can be compared to tree rings because they can tell how old a certain specie or individual is.
As to how that could have happened, it's unclear. A likely possibility is the occurrence of a sudden event that caused large-scale environmental trauma and wiped out majority of the Earth's species."
Next they'll tell us something crazy like every culture has a flood story.
So, yes or no?:
You do understand.that he is only talking about extant species.... right?
You do understand that many other species have lived on this planet .... right?
You do understand that the number of species alive today represents about 0.1% of the species which have ever lived... right?
So you don't know much. That's OK, stick around and follow me, I'll edjewmicate you.
Yes, pease do, professor. Educate me. tell me what you are going to say to the person who names 4 animals that were alive 400,000 years ago. go on, regale us.
But when you are done:
You do understand that he is only talking about extant species.... right?
You do understand that many other species have lived on this planet .... right?
You do understand that the number of species alive today represents about 0.1% of the species which have ever lived... right?
You did start this thread for discussion... right? So, answer the questions.
