There are basically three types of evolution divergent, convergent and parallel evolution.
a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
A, because, the entire point of his theory was to prove that changes don't happen spotaneously!
First, a complete digestive system means that the digestive tract has a beginning or the oral end and the opposite end or the aboral end. This is found in more complex animals starting from roundworms (flatworms have an incomplete digestive tract). A closed circulatory system is found in animals more recent than mollusks. The presence of the coelom makes it more evolved than the flatworms.
Specifically, a small animal with a segmented body, short stiff appendages, and soft skin with the above characteristics point out to the phylum Annelida or annelids.
