At present, British scientists have put forward a view that sponges have no brain or even any nerve cells. An animal that has lived on the earth for hundreds of millions of years also had nerve cells in ancient times, but gave up in subsequent evolution. If the following are true, which of the following is most supportive of this view is:. ['ponge has the genes needed to build the nervous system, and for the sponge, whether it is the brain or the simple nervous system, it can be a "cumbersome" and a waste of energy.', 'ow it is found that the jellyfish with a complex nervous system is the "sister group" of all other animals and the best representative of animal ancestors.', 'he oldest known animals with complex brains appear much earlier than sponges. They have sophisticated brain-like structures and specialized neural networks.', 'Some parasites have lost their complex nervous system due to the parasitic lifestyle compared to their close relatives; sponges have a lifestyle similar to parasitic compared to their close relatives.']
