Jacob was studying a timeline that represented the history of life. His assignment was to use logic to interpret the patterns he saw there. The timeline showed that during a period of time
called the Cambrian period, many new species of multicellular animals suddenly appeared in the fossil record. Some of the multicellular animals that appeared in the fossil record
before the Cambrian period shared similar traits with some of the new species that appeared in the fossil record during the Cambrian period. Which statement is a logical interpretation
of these facts?
O The species that lived in the Cambrian period are still living today
O The species that lived in the Cambrian period were unrelated to the species that lived prior to that period
O The species that lived in the Cambrian period were ancestors of the species that lived prior to that period
The species that lived in the Cambrian period could have descended from the species that Ived prior to that period
