Duck-billed platypus（鸭嘴兽）:The first scientists t examine a preserved platypus bdy judged it a fake in the late 18th century. The ldest discvered fssil f the mdern platypus dates back t abut 100,000 years ag.The duck-billed platypus is a small egg-laying mammal (up t 60 cm in length) fund nly in Eastern Australia including Tasmania.

2.The yung man in questin, Charles Darwin, was a gelgist and naturalist, fascinated by rcks, plants and animals. He left England n the ship, the Beagle, in 1831. The jurney gave him the chance t study varius living things in their natural envirnments. After Darwin had spent sme time in Suth America, his rm n the ship was crwded with samples f the plants and animals he had cllected. As he studied these, he asked himself the questin: hw did different species cme t exist?

Hw did different species cme t exist?
Samples f the plants and animals
All species had appeared n Earth at the same time, and had nt changed since.
Animals evlved as they adapted t their changing envirnments.
T lk fr mre evidence.
3.At that time, peple believed that all species had appeared n Earth at the same time, and had nt changed since. But Darwin began t think differently. He nticed that sme species f animals were very similar t each ther. Maybe animals evlved as they adapted t their changing envirnments? It was just an idea, but enugh t inspire Darwin t lk fr mre evidence.
Darwin nticed finches’ beaks had evlved accrding t what fd was available n that particular island.
New species f plants and animals evlved frm earlier ancestrs.
4.When the Beagle reached the Galápags Islands in 1835, Darwin saw a variety f new species, but it was the birds that interested him the mst. Darwin nticed that there was a difference between the finches n each f the islands. It seemed their beaks had evlved accrding t what fd was available n that particular suspected that the finches had evlved frm a cmmn ancestr, which had arrived n the islands a lng time befre. Over time, it had slwly evlved int many new species. And that was the answer t hw new species f plants and animals came t exist: they evlved frm earlier ancestrs.
