Answer:
The environment selects the lineage which better fits their specializations in the available resources.
Explanation:
The possible motive that lineages demonstrated quickly diversification might happen because the environment contained the opportunities which the lineages took as an opportunity to evolve. The environment could have benefited some species rather than others which could lead to different specializations of different lineages. For example, after the downfall of the dominance of dinosaurs, mammals had a few new environments to evolve with new resources, this led to more lineage biodiversification.
Explanation:
The mules are the hybrid of the horse and donkey. The horse female gamete cell contains 32 chromosomes whereas the donkey sperm cell contains 31 chromosomes.
The hybrid produced shows that the donkeys and horses shared the recent common ancestor.
The mules are infertile organisms as their gametes are not formed properly due to the difference in the number of chromosomes of the male and female gamete.
The gametes are produced by the process of meiosis which involves the pairing of homologous chromosomes but chromosomes fail to pair because of one extra chromosome which fails to for homologous pair.
The mitosis is possible in the organism as the mitosis process does not involve the pairing.
