EVOLUTION CONNECTION Living members of a vertebrate lineage can be very different from early members of the lineage, and evolutionary reversals (character losses) are common. Give examples that illustrate these observations, and explain their evolutionary causes.

Question

Accepted Answer

Hello everyone here We have a question asking an example of evolutionary reversals during the course of vertebrate evolution is a. The well developing flippers. B four limbs developing into wings and birds. See fins developing into limbs and tetrapods. Or the loss of functions of appendix return from an advance to a more primitive character. Is referred to as an evolutionary reversal, whales were tetrapods which developed limbs that then we reverted back to flippers. So this is an evolutionary reversal. Be four limbs developing into wings and birds. This isn't an evolutionary reversal because it's changed to more advanced character. See fins developing into limbs and tetrapods again this is developing into more advance. They lost the function of appendix. This is the loss of a function of a structure due to not using an organ is not an evolutionary reversal. So our answer here is a well developing flippers. Thank you for watching. Bye.
