- In a courtroom in 2005, biologist Ken Miller criticized the claims of intelligent design. After noting that 99.9% of the organisms that have ever lived on earth are now extinct, he said that “an intelligent designer who designed things, 99.9% of which didn’t last, certainly wouldn’t be very intelligent.” Evaluate Miller’s criticism.arrow_forwardChoose one of the misconceptions and explain the misconception and how discuss how your understanding on this misconception has developed over time. 1. "Scientific understand is unchanging." 2. “All mutations have an impact on the organism.” 3. “Natural selection involves organisms trying to adapt.” 4. “Adaptations are a result of competition.” 5. “There are more consumers than producers.” 6.
