Glad you're here, to share explorations of life. If you're registered in Biology 103 , remember to log in before posting here. Others are welcome to contribute without logging in. Such comments though will be checked to avoid spam postings and so be delayed in appearing.
In any case, remember that this isn't a place for polished writing or final words. Its a place for thoughts in progress: questions, ideas you had in class (or afterwords), things you've heard or read or seen that you think others might find interesting. Think of it as a public conversation, a place to put things from your own mind that others might find useful and to find things from others (in our class and elsewhere) that you might find useful. And a place we can always go back to to see what we were thinking before and how our conversations have affected that. Looking forward to seeing where we go, and hoping you are too.
You're free to write about anything that came into your mind this week. But if you need something to get you started, what did you think of our survey of scales of space and time relevant to living things? Of the diversity of living things?
