During the nineteenth century, biologists knew that South America and Africa contained similar fossils. These fossils led them to believe that a temporary land
bridge between South America and Africa allowed ancient species to move
between both continents. In the twentieth century, evidence showed that South
America and Africa were once part of the same larger continent and that there
were no land bridges between them. How should biologists respond to the new
geological finding?

D: Biologists should update the history of life, because it should include the new geological finding.

Explanation:

hope this helps :)

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

the fossil record provides evidence of a common ancestor to many species.
