week 6 homework DNA doesn't determine race

I pretty much agree with it. American born/grown Asians are just like American, nothing like Asian.

I mean their life style, habit, philosophy are just American!

week 6 homework how to distinguish living and non-living

living things propagate, where non-living things don't.

week 5 homework chicken first or egg first

eggs first, although its parents might not be chickens.

Here is another example of our new idea, sudden mutation from currently existing species.

week 5 homework how i think new species emerge

I think new species emerge by sudden mutation from currently existing species.

But I also think unlike evolution theory, the mutation itself does not have to be in order to adapt to current challenges--it can occur randomly(in the sense we never know why it happened. Maybe God knows)

For these weeks we read a lot of articles about species, but scientists and researchers still need some more steps to get there.

week 4 homework post thoughts on how we view animal intelligence

For long time we have not paid that much attention to animal intelligence.

Maybe because it doesn't make any money

Or maybe it does not interest many scientists.

Now things are different.

Quite a few scientist began to pay attention to research for animal intelligence, and they found actually they are way smarter than we thought.

week 3 homework Post a comment on one of this morning's discussions

Meat made from stem cells

purely lab-grown burger gives me new insight of future food solution and potential business opportunity.

Still costing too much, $385000, but eventually as technology grows this will be reduced dramatically.

We need meat! 

week 3 homework check out http://www.biology.arizona.edu/cell_bio/tutorials/pev/page2.html

Interesting homepage telling us how different our life and sexual style will be if we were bacterias.

The page clearly shows the difficulties of bacteria life by converting ourselves in them for simulation. 

week 3 homework 99.4% of the most critical dna sites are identical in human and chimp genes

Nothing surprising.

Many scientists have been telling us we and apes are very close, perhaps we are part of apes.

So it's not completely new idea, just an extension of what we already knew.
