  • Q6
    Wild Soay sheep live in a cold environment on a small Scottish island. The sheep used to be large because they gained extra weight during the summers in order to survive the harsh winters. A recent change in the island’s climate has caused grass to be available for a longer period each year, so survival conditions for the sheep have become less challenging. Researchers who study these sheep have most likely observed a decrease in the wild Soay’s -
    size
    life expectancy
    body temperature
    reproduction rates

    A fossil found in a surface rock layer is of the same species as a fossil found in a deeper rock layer. However, the two fossils differ slightly in structure. Differences in the structures of the fossils indicate that
    the species had many predators
    the food supply of this species changed
    the species changed over time
    the life span of this species changed
