Question

3. Check your understanding Discuss each answer in your group - correct or not and why? Explain in 1-2 sentences per answer. 1. Which of the following is a true statement? a. Only cells that make a specific gene product, like a protein, carry that gene. b. Through natural selection and time, evolution can produce seemingly complex adaptations through gene duplication and recruitment. c. Scientists do not debate the evidence for evolution; they accept the theory of evolutionary biology on faith d. Evolutionary biologists believe that pure randomness can produce complex adaptations, like the eye.

Answer 1

1 a- False

  Different cells in a multicellular organism can show different sets of genes, even they contain the same DNA.

b- True

In a genome experiment, the fitness effects of deleting pairs of duplicate genes and deleting individual genes from the yeast genome, summarise that duplication rarely results in adaptation

c- True

yes, they accepted the theory of evolution on faith but not all scientist has accepted.

d- True

Yes, pure randomness can produce the complex adaptation.
