0:58.1 | Since at least the early 90s, when the full discovery of the Chick-Sloob crater gave weight |
1:03.5 | to the impact hypothesis, it's been pretty universally agreed that non-avian dinosaurs |
1:08.9 | went extinct 66 million years ago due to a huge comets or |
1:13.5 | asteroid. But a question that comes up every now and then is if there were other factors at play |
1:19.5 | in their extinction leading up to the impact event. At the end of last month, a new paper was |
1:25.0 | published in the journal Nature Communications that argues that dinosaurs had already been in decline for 10 million years leading up to the asteroid impact, a combination of climate change and decreasing biodiversity. |
1:39.5 | Quoting inverse. |
1:40.9 | Further analyses indicate that the global dinosaur decline could have been precipitated |
1:45.2 | by the decline of herbivores, explains lead author Fabian Condamine, a research scientist at the |
1:50.7 | French National Center for Scientific Research, adding that herbivores are essential keystone species |
1:56.6 | in ecosystems. His research suggests dinosaurs weren't able to recover from these dual blows. |
2:03.2 | The rates of new species of dinosaurs emerging could not keep up with the extinction rates, |
2:08.4 | leading to a decline in dinosaur diversity. In fact, the dinosaur decline was so severe. Condamine |
2:13.7 | and his colleagues posit that the T-Rex may have only had one species left on planet Earth |
