Tue, 12 May 2009 03:34:34 +0000 http://slesscience.edublogs.org/?p=179#comment-773 Hey Mr. Kremer, Here are the answers to 2 of the discussion questions... 2) Evolution occurs extremely quickly in bacteria and people can observe it. Almost all other living things reproduce too slow for people to observe evolution of that species. Also I agree with Emma when she said viruses evolve very quickly to adjust to the medicines people take. I don't know if people can actually observe viruses evolving but it happens fast enough that someone could observe it. 4) Scientists look at fossils and rock formations like cliffs or canyons. They test them to see how long they have been around. They can also test regular rocks that they maybe found underground to see how long those rocks have been there. and for the responding to someone else's post... Claudia, bacteria don't observe evolution... people observe the bacteria evolving... :) -ana k. Hey Mr. Kremer,

If you can help me get onto it then I can stay after school to work on it. Mr. Kremer,

Evolution can be observed in bacteria. 4. Scientists can look at rock formations in places like the Grand Canyon and determine events that happened to the earth billions of years ago. They can also test rocks to see how old they are. Scientists can even look at fossils to observe what life was like billions of years ago on planet earth. I would like to add to my comment.

Don't just agree with them! -Mr. K Class,

Yes i do believe that evolution can occur so quickly that bacteria can observe it. 4. I think that scientist came up with the Earth being 5.6 billion years old by studing fosslis and calculating the year of those fossils. sorry Mr. K I posted incorrectly here are my answers to 2 and 4

I like how he gave three ways that geologists can find out about evolution. I agree with Chris’ answer for number 4. I like how he gave three ways that geologists can find out about evolution.

I agree with your post on both of the questions. They seem reasonable and unique to me. I like what you put about the hydrothermal vents. I also like the concept of using carbon dating to find out how old the Earth roughly is. :) Hey Nat!

In a hydrothermal vent, life would be very, very different. I think Natalie was right with her answer to Number 5. In a hydrothermal vent, life would be very, very different.
