In my anatomy class (for art) today, we had a discussion about the possibilities of evolution in other planets. Basically, astrobiology. Anyway, to get the point, I ended up wondering, should a planet be mostly made up of water (well, more than Earth's) and life were forced to evolve IN the water itself instead of our evolution theory from fish to amphibian to reptile, etc., what do you think the beings would look like having evolved completely underwater?

Would they look like the creature from the Black Lagoon, or Abe Sapien of the Hellboy series? Maybe Lovecraft's tentacled Cthulhu? Would they be half fish, like a mermaid of the Disney creations or a more fish-like being in the Harry Potter movies? Ofcourse these examples are just a joke, haha.

But what are your thoughts? Don't be afraid to wander in fantastic possibilities, just make sure it makes sense evolutionary-wise. And just to be clear, this is astrobiology, which is science, not magic and fiction.

Students prepared streak plates to determine the oxygen requirements of Bacillus bob. The plates were incubated at 37degrees C for 48hrs. The students removed the plates from the jars and incubator on Friday, recorded their results and left them on their shelf.
Incubator had heavy growth
Anaroebic Jar had light growth

A student was absent on Frieday and looked at the plates on Monday. She told her group they read the plates wrong and both of their original results should have had heavy growth. Would you agree and change your answer?? Please Explain!!

here's the scenario: male A impregnates female A, that fertilized egg is removed from female A. the egg is placed in female B to carry to term. Now does the child have any genetic connection to female B, seeing as female B's blood is probably throbbing in child's veins? if a maternity test were done, would it identify two mothers?
