O the mainland
On an island, a scientist observes that the native lizards are different from similar species that live on the nearby mainland. The scientist concludes that the common ancestors of the lizards
began developing into different species when the island separated from the
Which evidence would best support the scientist's conclusion?
Fossils of the same lizard species on both the island and mainland
Geologic evidence that the island arose from a volcanic eruption
The appearance of a mainland lizard living on the island
The appearance of an island lizard living on the mainland

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
