Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change.

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.

What is the missing word? Fossils can show how organisms have gradually changed over a long period of time. This process is called __________.

Darwin's theory of natural selection has long been a guiding light for explaining changes in species over time. These changes happen for a number of reasons and are usually based on selective pressure.Which of the following examples is NOT an instance of natural selection?Elimination ToolSelect one answerAA group of giraffes stretching their necks in order to reach more leaves to eat.BA shift in the coloring of beetles over time to blend in with the leaves.CMore nocturnal mice in an area over time due to the presence of daytime predators.DA group of gophers getting smaller over time because they can hide in caves from predators.

Over a long period of time, helpful variations in a species replace the unfavorable ones. This change can lead toGroup of answer choicesgenetic mutations.fossilization.geographic isolation.evolution.
