Which of the following best describes the fossil record?Multiple choice question.It is a complete record of species that have existed on Earth.It is incomplete, except for a few types of organisms such as horses, whales, and humans.It is an incomplete record of species that have existed on Earth.

Which statement about the fossil record is true?Choose 1 answer:Choose 1 answer:(Choice A)   The fossil record can show roughly when species appeared but not when they went extinct.AThe fossil record can show roughly when species appeared but not when they went extinct.(Choice B)   The fossil record shows that life has existed on Earth for billions of years.BThe fossil record shows that life has existed on Earth for billions of years.(Choice C)   The fossil record is made up of a subset of the fossils that have been found on Earth.CThe fossil record is made up of a subset of the fossils that have been found on Earth.12 of 30SkipCheck

Select all that applySelect all of the following that explain why the fossil record is incomplete.Multiple select question.Many organisms decomposed before they were buried in sediments.Erosion and movements of the Earth's surface have destroyed many fossils that did form.Fossils were not formed south of the Wallace Line due to proximity to the equator.Many fossils may never be discovered because they are buried deeply or submerged under water.Fossils older than 100 million years old have already decayed past the point of recognition.

Which statement accurately describes the fossil record and its contribution to our understanding of natural selection?Multiple choice question.Paleontologists have found a number of transitional fossils at the predicted positions of time.Scientists have found several transitional fossils, however, they are not located in the predicted positions in time.While the fossil record has greatly improved, scientists have yet to find a good transitional fossil that supports evolution by natural selection.

A potential problem with the phylogenetic species concept is that Blank______.Multiple choice question.it is difficult to determine if fossil populations are monophyletic with extant populationsit will result in very large species, comprising hundreds of populations, as long as they are monophyleticit may recognize even slightly differentiated populations as separate species

Which is a reason that many organisms that have existed on Earth have left no fossils?A.Fossils cannot form underwater.B.Many organisms live only in rainforests.C.Fossils can only form near volcanoes.D.Fossils decay according to their half-life
