Jean Lamarck and Charles Darwin both thought and had ideas how life on Earth got to be the way it is now. They had similar and some different idea.
Hey, Darwin!
oh! mine is that all species of organism arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce
Yeah, we have some samilar idea and some differences.
Well, my discovery is based on the physical changes inorganismsduring their lifetime, you know the development of organ could transmitted through to their offspring
Let's talk about our discoveries Darwin, I know you've done a lot
Let me explain my discovery Mr. Jean Lamarck
How do you say so, Mr. Charles Darwin?
Most elephants used to have short trunks, but some had longer trunks. When there was no food or water that they could reach with their short trunks, the ones with short trunks died off, and the ones with long trunks survived and reproduced. Eventually, all of the elephants had long trunks.
I believe that evolution does not happen according to any sort of plan
oh nice!
Would you like to share your ideas too?
Sure, Mr. Darwin
I beleive that giraffes stretched their necks to reach food. Their offspring and later generations inherited the resulting long necks
