In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation. A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring. B. Speciation has occurred because breeding between the offspring and original populations would not be possible. C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area. D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
