This is an open forum area for all members for discussions on all issues of science and origins.

This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.

As usual, Tweb rules apply. If you haven't read them now would be a good time.

    Oldest common ancestor of spiders, scorpions, horseshoe crabs found in Burgess Shale. Neat picture!

    Does the article or its title imply that other crabs have a different ancestry ? Spiders give me the creeps, but they are amazing creatures to have survived so long.
