Biologic evolution

It is an every time familiar mussel.

Though the research of the mussel is happy

Next, it thinks what you do now.

There is no material though it thought about the fish bone.

It was not found though it browsed in the bookstore.

Wikipedia is embarrassed because it is not found though examined.

The specimen only of the bone that had taken fish's internal organs was seen.

I thought that the possibility that the shellfish like the mussel evolved to
the fish was high.

When the possibility that Tait becomes a bone can be proven, it is good.

Is this problem amateur's limit?

I want you to see the part of sand in the photograph.

It will be brown.

This is not a color of sand.

They are the excrements of shellfishes that keep it in the water tank.

The shellfish also eats, it digests, and excrement is put out.
