I am C.J. and I LOVE to hunt. I also like to play sports and ride dirtbikes.

My favorite topic this year has been operant conditioning. I like watching the animals learn through trial and error how to do something. The video below does a great job showing a dog learn how to roll over through trial and error.
Here is a little clip of a protien getting modified as it moves through the golgi. The shape it turns into is determined by where it is going to be shipped in the body.
Whales on Land
Around 47.5 years ago modern whales were land dwellers.
a palaeontologist at the University of Michigan in Ann Arbor, whose team found the fossil of the mother and calf in north-eastern Pakistan. The fetus in the fossil proves that whales use to be land dwellers. Maicatetus inuus meaning “mother whale" represents an intermediate evolutionary stage. It often moved back and forth from land to water in what is Pakistan today.
The fossil had a long snout, short hair, short limbs, webbed hands and feet, and a thick long tail. Unlike modern whales this one used its feet to swim. Philip Gingerich stated that it probably lived like a sea lion, spending part of the day or night searching for food in the water and part of day or night resting on land.
Unlike modern whales the fetus in the fossil was positioned “head first”. That gave the biggest clue that the fossil gave birth on land. The fetus also had a set of developed teeth suggesting that after birth it would be ready to keep up with its mother, learning how to feed and escape predators. Gingerich said, “It would also have to protect itself from very large sharks.
Why did whales start going to the water? Philip Gingerich answered that question when I emailed him about it. He said “That while the whales were on land they would eat dead fish on shore. Then that led to them catching dying fish in shallow water, then more active fish further out, and so forth” but it took many generations. Once they got really far out it was not worth going back to shore to have babies and rest.
For my bitstrip to be bigger go
Was there not enough food on land so they were forced to the water? How did different types of whales evolve?
This is a really good post you might want to add some creativity like an animoto and source you second and third paragraph-Teddy
How Will I Meet This Expectation?
How Did I Meet This Expectation?
Demonstrate ability to
evaluate sources of
biology information on
- I will put my sources on credible sources to page to getapproved before using.
- I will check the credible sources page and and say if the
websites on it are reliable or not.
- I put a source on the credible source page
- For my post I used a source that was on the credible
source page and that was approved.
Demonstrate an ability
to read and understand
current biology news
- I will look up anything that I do not understand.
- I will find a way to describe in a way so that everyone can
- I had a question about whales on landand since it is a newer
topic there isn't much I emailed the palaeontologist who found the remains with his team.
use of online resources
- I will only use reliable sources
- I will critique others sources
- I will be careful using sources that dont end with reliable
The source I used on my blog was reliable and had been checked by classmates.
Publish work that is
available for peer-review
- Before I post my blog I will have a few
people review it to make sure it is interesting
I put my post on the discussion board and got classmates to review and approve it.
Discuss published work
with a practicing biologist
in that particular field
- I will contact the author of the source I use if I have any
- I will talk to some one who has experience on my topic.
- On my post about whales on land I had a few
questions so I emailed Philip Gingerich who is a
palaeontologist at the University of Michigan in Ann Arbor,
whose team found the fossilised mother and calf in north-eastern Pakistan.
He answered my questions and wrote back. He has a lot of experience
on this topic.
- I will help someone create a blog before it
is up so that i can give them advice to help make it
- I will comment on classmates post.
- The blog I make will be about something
we are learning about in class.
- My comments will relate to class
The post whales on land is all about evolution. We have recently been discussing evolution in class
-I will make a bitstrip realting to my post
I added a bitstrip to my post it is also on my
help on how to format text
