When did the fossils of the Galápagos Islands form?
—The question of age is a sensitive issue for creationists.
Two important elements inform a possible answer that probably most creationists would embrace.
First, the fossils appear to be relatively young, being found in deposits that are often within recent features of the landscape (e.g., lava tubes, craters) and associated with Pleistocene and Holocene radiometric ages.
The second, called relative dating, tries to establish if the object is younger or older than other objects but without assigning a specific numerical age.
Absolute ages in geology are based on radiometric dating methods.
These tunnels and fissures often contain sediment with fossil remains of terrestrial vertebrates .
