It's true.

"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion."

Carl Sagan (1934 - 1996), 1987 CSICOP Keynote Address

Thursday UPDATED

So today the plan was:
  1. Finish video
  2. Start 10.4 Notes
  3. Do this homologous structures activity:
Homologous Structures Activity

However, TWO HOUR LATE START.

Also, the link doesn't work from S-3 computers.  Therefore, I will be handing out the worksheets and if you complete this by Wednesday, it's worth 2 extra points.  :-P 2 points you say?  Ask anyone whose grade didn't round up .01% last quarter. peer student pressure: it'll be worth 4, which is as much as any of the worksheets this week.

Today WE DID:
  1. Finish video
  2. Some of us: started 10.4 Notes
FOR TOMORROW:
  1. 10.4 Study Guide Due
