There is no advantage to an organism in having part of a wing or part of an eye.

in my opnion eyes are better than wings

Explanation:

because if we have wings no eyes so how could we see the nature in the sky but if we have eyes we could see the lands beauty instead iof sky

                                      eyes are better alhammahduliallah

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
