the evolution from RNA to DNa was very interesting. We seemed to have focused
very little on this in HS. Well done here.
I really enjoyed the examples and theories.
It was fair to repeat that all eons and era were estimates
and as improvements in sciences technologies so will the precision
in our evolutional history.
I LIKED LEARNING ABOUT RNA AND RIBOZYMES
It was cool to learn about how simple organic compounds were created through natural events happening in the time of the early world
What I liked about this lesson most of all was the amount of possible steps it took for the evolution of life in our world.
it was great to see how oxygen helped form the ccreation of life early.
