Biologic evolution

There was a program "Science loving soil way cram school" last
Saturday.
The content is Mr.Kenichiro Mogi. 『It is Hen. Alive the one at
great antiquity』｡
The living thing of the sea of the great antiquity was broadcast.
Because I had been interested in the biological evolution, the
program was seen.
An ancient living thing that exists for a long time in sand in the
program is seen.
"Taconomacra" of the sea urchin starfishes that would introduce it in
the future was recalled.

Any ancient living thing was a living thing only it was without doing
in sand.
The name has been forgotten.
Not being possible to introduce it is regrettable because it did not
record though it searched for the homepage of NHK education.
