Planet of the Dinosaurs

Good thing we'll be gone when big, scary dinos come back. Like not being at the top of the food chain sucks.

Evolution of Homer Simpson

Dinosaurs or dinosaur-like organisms will evolve again because of climate change and mass extinction caused by human activity, creating a situation similar to that of the early Triassic.

When y'all realize humans will be extinct someday.

The percentage of threatened mammal species is around 4 times the percentage of threatened reptile species.

This makes it possible for species other than birds to develop dinosaur-like characteristics.

Convergent evolution between marsupials from Australia and placental mammals from elsewhere.

Flight and bird-like hips are excellent examples of convergent evolution.

Megalania prisca, one of the varanid lizards that dominated Plio-Pleistocene Australia.

Peppered moths during the Industrial Revolution is a recent example of a species reverting back to its original form.

Pterosaur (1), bat (2), and bird (3) wings.

Birds, pterosaurs, and bats are all distantly related organisms that have developed the similar characteristics of flight and wings.

Another theory is that, before flight, some bird-like coelurosaurs and early birds glided from tree to tree in search of food. Eventually this led to the development of wings and flight.

If modern birds had teeth. Like seriously. A horde of birds with teeth flying towards you.
