Student Expectations
How Will I Meet This Expectation?
How Did I Meet This Expectation?
Demonstrate ability to evaluate sources of biology information on the internet
I will check if the are credible sources and if the authors are knowledgeable about what they are writing about by checking their educational background.
I have checked many different websites on the credible sources page and have approved them. I have also have reviewed Phoenixia and Jesse's posts. I have checked my own sources for my post by seeing where they got their information and what the main topic for that website is to see if would specializes in my topic.
Demonstrate an ability to read and understand current biology news
I will read and look up any words I don't understand in the article then re-read it to assure my understanding of the subject.
I have read over my sources many times to make sure that I am familiar with the information.
Demonstrate proper use of online resources
I will use hyper links on information that i got from a particular site.
I have hyper linked my picture and added hyper links into my section on giraffe evolution to show views where I got my information
Publish work that is available for peer-review
I will make my work public so it may be viewed for mistakes that I may have made with information of proper language.
I have posted my blog project on this wiki page so it can be viewed by classmates and anyone in the public. It is also open to review by my class mates.
Discuss published work with a practicing biologist in that particular field
I will find a scientist in the field being discussed and have a conversation about the subject.
I have emailed a scientist Dr. Jason Rosenhouse. He was very helpful and sent me a whole paper that some one has written on my exact topic.
Provide constructive peer-review to classmates
I will look over my peers work to check for mistakes or miss use of information and give constructive criticism.
I have done this for two of my class mates, Phoenixia and Jesse
Discuss in-class assignments
I will use the information from class to discuss with different people to become more informed on the subject.
We have discussed evolution a lot in class and have shared our ideas about the projects many times.
Apply creativity to work
I will be unique and take my own pictures instead of using the publicly displayed images on the internet to make my work more interesting to learn about.
I have added a picture of a drawing I did on the computer of a giraffe.




Hello, I'm Michael. I am a very athletic person. My favorite sport is snowboarding, but I also like basketball and soccer and my favorite
animal is a dolphin.

Lamarck: Giraffe Evolution

giraffe.jpg

Jean-Baptiste Lamarck was one of the first scientists to bring up a theory of evolution. Later came Darwin who had a better theory that is still used today. The reason Darwin’s theory was accepted was because he had more data and a better explanation than Lamarck, but what was Lamarck’s theory? What was his data that made his theory one of the first accepted explanations? Well one of his great examples was the evolution of giraffes long necks.

The giraffe neck seemed to be a straightforward sign of evolution. Lamarck had given his explanation of giraffes growing necks in his book about his theory of evolution. This is a small quote from his book, Philosophie Zoologique. “It is interesting to observe the result of habit in the peculiar shape and size of the giraffe: this animal, the tallest of the mammals, is known to live in the interior of Africa in places where the soil is nearly always arid and barren, so that it is obliged to browse on the leaves of trees and to make constant efforts to reach them. From this habit long maintained in all its race, it has resulted that the animal's forelegs have become longer than its hind-legs, and that its neck is lengthened to such a degree that the giraffe, without standing up on its hind-legs, attains a height of six meters.”

This shows Lamarck's belief of how he thought animals got the traits they needed to survive. If giraffes needed to stretch their necks to reach leaves, after generations of stretching their necks the trait would be pass down through the next and form then on be passed through the generations. We now know that is not true and that those who don't have these traits in a species die off. Those in that particular species who have the trait will survive and reproduce which will over time show more of this species with that trait. That is Darwin's theory, Lamarck had did not have the evidence that Darwin had, so he could not come to the conclusion that Darwin did which is why Lamarck's theory was later replaced by Darwin's.

Questions

  • What would the world be like today if Darwin had never published his theory, would our thoughts and studies be different today?

  • What was the evidence that Lamarck have that made his theory accepted in the first place?

  • What are the similarities between the two theories?

This post is very well thought out, if we never had these ideas the world studies would be completely different because evidence is everything is Science because the more you have supporting your idea makes it better. Lamarck had the belief how he thought animals got the traits they needed to survive such as long necks in order eat. The similarities between these lack but this is a great post and there isn't anything I can see that has to be changed.
