1) Ancient Sponge was the organism thought to be the first multi-cellular animal.
2) The alikes from animals today: The differences from animals today:
Sponges reproduce lke animals today. Sponges cells come together (Reinvent) Sponges has prey on other animals for food. Sponges does not have a brain, head,etc. Sponges have a heart like other animals do. Sponges pumps water for food (Fast)(2secs)
3) Scientist know it's an animal because it has a heart, reproduces, and preys on other animals for food.
4) DNA is the evidence that can prove that other animals evolved from this organism.
5) I want to know how other animals can evolve from a sponge when a sponge is simple. other animals move around alot and is just very different from a sponge.

Hi Hi! Yes, I agree with you how a sponge is very simple. But just imagine how it has a heart. That just makes it even more interesting huh Well now we can be more motivated to do some more research! :)
