Choose 1 answer: organism complexity and diversity have increased. A. organism complexity and diversity have increased. organism complexity and diversity have stayed roughly the same. B. organism complexity and diversity have stayed roughly the same. organism complexity and diversity have decreased. C. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other. Fossils can also be used to date rocks. Through the process of evolution, different kinds of fossils occur in rocks of different ages, enabling geologists to use fossils ...Fossils can be found in surprising places and they can tell us about the past.

The Fossil Record. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record. The fossil record was one of the early sources of data underlying the study of evolution and continues to be relevant to the history ... The explanation lies, as I believe, in the extreme imperfection of the geological record. Charles Darwin (1859), The Origin of Species, p. 280. Darwin's statement acknowledges an incomplete fossil record rather than a problem with his theory.The use of temporal information from the fossil record as data in phylogenetic inference has been criticised however, with concerns ranging from the incompleteness of the geological record to the non-clocklike evolution of morphology . Inferring the phylogenetic position of fossils can only be achieved using morphological …The fossil record is a book with lots of pages missing.
