The current mass extinction event, caused by human activities, threatens biodiversity, with global efforts aiming to mitigate the crisis by 2030.
Insights
- Dinosaurs, originating around 230-240 million years ago, ruled Earth for over 170 million years, with the Cretaceous period being the most diverse before an asteroid strike led to their extinction 66 million years ago.
- Birds, considered descendants of dinosaurs, evolved from flying dinosaurs like Archaeopteryx, with studies identifying chickens and ostriches as the closest living relatives to dinosaurs, showcasing the evolutionary link between these ancient creatures and modern avian species.
