Polar Bears Older than Thought

By Ava D.


A large male polar bear returns to feed on a fin whale carcass. On land, where bears cannot hunt for seals, food is scarce and polar bears mainly depend on washed up marine mammals for food. Holmiabukta Bay, Northwestern Svalbard, Norway.

I thought that this was very cool. I didn't know this about Polar Bears at all. Good night people!!! I do not want to wake up tomorrow at 3:30 a.m.!!! BYE! BEDDY-BYE!

I think this was very interesting and cool! I had no idea about any of this so I found this very informative. In all I found this interesting and something that I would have never known.

I thought that this article was very interesting. Before, I never knew about polar bears separating from brown bears. It is possible that either theory about when polar bears first separated from brown bears could be more accurate than the other. This article gives evidence that the latest dating is correct, and it makes sense, however there could also be a lot of evidence that the other theory is more accurate, but the article does not mention any of it. I think that if the scientists made one little mistake, it could have completely messed up their results. This shows just how meticulous scientists have to be.

This article is very cool. I never knew that polar bears and brown bears lived close to each other. It's interesting to think that ice was already melting without us humans polluting much.

This was an interesting article. I never knew that polar and brown bears were once interbred.

If you look at the fast facts, you will be able to see that both facts are really similar. The only major difference was the diet and the weight. I was curious what "BEDDY-BYE" is. Can anyone tell me what Camille meant?
