Cambrian fossil shows parent caring for young


From Jasmin Fox Skelly at New Scientist:

A 520-million-year-old fossil shows an ancient shrimp-like creature caring for its four offspring. It is the oldest ever example of a parent actively looking after its young after they hatch. More. (paywall)

The arthropod may be the ancestor of insects and spiders (or maybe not). We have one “snapshot” and that’s from billions of lives.

What it mainly shows is that, contrary to what we might expect, there seems to have been little evolution of animal psychology since then.

You guys might be right. It could be a mistaken assumption. But if they are prepared to entertain the idea that it isn't... News
One clump of matter is parenting four other clumps of matter, because the surrounding matter made it so. How cute. Origenes
PaV- It makes sense in an intelligently designed world. I was just surprised/ amazed that they think they could tell from fossils seeing as any number of events could have led to the placement. ET
ET: I suspect that actual present-day observation of shrimps led them to their conclusion. PaV
Question, how do they know the "parent" was not running away as fast as possible from the younguns? DATCG
awwww, now we know why we care for our children. Caring feelings and emotions, responsibility, and love evolved from a cute little bugsy wugsy blind, unguided evolution is grand, thank the random mutations we know how to care for our young. DATCG
Was it really parenting or were the little ones just following the big one to get scraps- and how can one tell? ET
So, now, even "parenting" appears out of nowhere. We await the "just-so" follow-up. PaV
Here's a brief look---first two pages---of the paper w being discussed. Here's a look at the fossils in question: here. PaV
