It has been found that certain proteins of the complex motor that drives bacterial flagella are modified versions of proteins that had previously belonged to plasma membrane pumps. This is evidence in support of the claim that

#Unit 11. Evolution and Behavior
  1. some structures are so complex that natural selection cannot, and will not, explain their origins.

  2. the power of natural selection allows it to act in an almost predictive fashion, producing organs that will be needed in future environments.

  3. the motors of bacterial flagella were originally synthesized abiotically.

  4. natural selection can produce new structures by cobbling together parts of other structures.

#Unit 8. Inheritance Biology

The pedigree shows the inheritance of a RFLP marker through three generations in a single family. A total of 8 alleles (numbered to the left of the blots) are present in the family. The RFLPs of each member of the family are placed directly below his (squares) or her (circles) symbol and RFLP numbers. In Above pedigree, which of the following are not children of second generation parent?
