Indiana is home to fossilized crinoids. These small, sea-dwelling invertebrates are vaguely reminiscent of starfish, and some species
of crinoid are still present on Earth today, but these animals were especially common in the world's oceans about 400 million years
ago. How is this information important to the theory of evolution?
C the presence of croons fossils

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
