Our variety of human beings (homo sapiens sapiens) and that other bunch (homo sapiens neandertalis) were both around 30,00 years ago, about the time that the "iceman" got frozen in the Alps. The present human genome varies little from that of the "iceman", showing that we never did breed with our probably equally-intelligent cousins, whose greatest cultural difference seems to be that they confined sex to a rutting season whereas it has always been "open season" with us. Were we mutually "ugly" to each other, or did breeding produce sterile offspring. (I can't imagine that there weren't curious people in both groups who experimented with it!)

said to be a primate ten feet tall, it's uncertain when he lived, if in fact it existed. evidence based on a few teeth is hardly sufficient to make a judgement - or am I wrong?

I'm and Engineer (Mechanical & Aerospace) - Project Coordinator

I have used autoCAD for over 10yrs...back to at least Release 11. So, I'm very good and fast in autoCAD. I was thinking it would be nice to be able to do some work on the side with it.

Does anyone do work on the side with AutoCAD for some extra cash? What do you do? How did you go about finding something to do?

Thanks

I am an incoming freshman and I want to take Algebra 2. I took Algebra 1 in 8th grade. Most people take geometry before Algebra 2. Is it possible for me to take Algebra 2 9th grade instead of 10th grade?
