Anybody happen to know if there is any evidence or signs or theories or hypothesis about when memory first evolved?

I remember seeing some nature documentary or other about early life, about the time when large, multicellular life likely first started coming onto land en masse, or somewhat earlier, that talked about a certain type of early fish developing memory. I forgot what its name was.

I'm trying to write a rather lengthy poem about evolution personified, and this would be a useful part of it to know, or know hypothesis about.

Paramecia are single celled organisms which belong to the ciliate phylum and have a memory of sorts. But no single cell organism is capable of any true, long lasting memory. For that, multicellular life had to develop. You may find this article on brain evolution from multicellular to mammalian life helpful.

Thanks a lot. This was just the sort of information I was looking for.

That's quite interesting about the paramecia. I hadn't been searching for that sort of info., but I'm glad I saw it. I hadn't considered single-celled organisms having what might be called varying degrees of cleverness before. I don't know why. I guess the concept just kind of slipped past my mind.

You're welcome. I'm glad I could help.
