Understanding ideasA Jurney f DiscveryReading
At the end f the class, yu will be able t:1. find ut the main idea f the text and specific infrmatin abut the jurney f discvery: the time and what the main character did r thught and summarize what kind f persn he was accrding t sme details.

evlutinary tree
5. What factrs can cause the prcess f evlutin?6. Can yu shw us a very famus persn related t evlutin?
Evlutin is nt nly a natural selectin prcess, but als the result f cmpetitin and cmmunicatin amng ppulatins

Paragraph 3: At that time Darwin began t think differently. It was just an idea, but enugh t inspire Darwin t lk fr mre evidence. Paragraph 4: Darwin nticed that there was a difference between the finches n each f the islands. It seemed that their beaks had evlved accrding t what fd was available n that particular island.
Paragraph 5: That was the answer t hw new species f plants and animals came t exist: they evlved frm earlier ancestrs. Paragraph 6: It was a cmpletely new idea—a thery f evlutin. Darwin explained this thery in his bk,On the Origin f Species. It was nt published until 1859.

3. Lk fr mre evidenceOn the Galápags Islands:• He nticed that there was a difference between the finches n each f the islands.• It seemed the beaks had evlved accrding t what fd was available n that particular island.
4. Develp ideasDarwin suspected that the finches had evlved frm a cmmn ancestr, which had arrived n the islands a lng time befre and it had slwly evlved int many new species.5. Prpse a theryThe Thery f Evlutin : living things, including humans, had evlved frm lwer frms f life.
