Summary
Scientists found fossils that are thought to be ancestors of T.rex. They are called reptorex
and have similar features with T.rex. The interesting thing is that their size is very small, a
little bigger than humans. Researchers suspect that they lived 125 million years ago. On the
other hand, T. rex is very big and lived 65 million years ago. The fossils of reptorex were
found in China (Ansari, 2009).
6. How does the article support the statement “the Earth’s present-day species developed
from earlier, distinctly different species”?
The article says that T.rex is thought to be developed from earlier species, reptorex. We
also assume that some present-day species, such as reptiles or birds, evolved from dinosaurs,
such as T.rex. Reptorex, T.rex, and current birds and reptiles are different, distinct
species from different ages. Therefore, the article supports the basic evolutionary theory
that each species evolved from earlier, distinctly different species.
