Question 15 (1 point) A scientist is studying the classification of three species of birds, labeled Bird A, Bird
B, and Bird C. According to a field guide on birds, Bird A and B are very closely
related while Bird C is a more distant relative. However, the scientist concludes that
the field guide is wrong, and that Birds A and C are the closest pair of
relatives. Which finding would provide the strongest evidence in support of the
scientist's conclusion?
17
2
Birds A and C share more genetically derived characters with one another than
with Bird B
15
Birds A and C are about the same size, while Bird B is much larger
O Birds A and C exist in large, healthy populations, while Bird B is endangered
O Birds A and C live together in the same region, while B lives farther away

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.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
