TIMELINE ENG
The estimated age of the Earth is about 4.5 billion years. The history of life on it is only slightly shorter. More than 95% of organisms that lived on the planet in the past are now extinct. The law of the irreversibility of evolution, formulated by Charles Darwin, excludes that the same animal may appear at multiple times on the Earth. As a consequence of this principle, trilobites, dinosaurs, and mammoths will never reappear. Can you match individual plants and animals to the periods in which they lived? Match the pictures of plants and animals to the periods from which they are known. Application marks a correct match.
