is the vaquita extinct 2022? The vaquita is the most endangered cetacean in the world.

WWF is urgently working to ensure they can live and thrive in their natural habitat.
What went extinct during the Devonian period? Changes in the late Devonian hit shallow, warm waters extremely hard and fossil records indicate that this is where the most extinction occurred. In all, about 20% of all marine families went extinct. Groups particularly impacted included jawless fish, brachiopods, ammonites, and trilobites.
What organisms first disappeared during the Devonian period? Bivalves, crinoid and blastoid echinoderms, graptolites, and trilobites were all present, though most groups of trilobites disappeared by the close of the Devonian. The Devonian is also notable for the rapid diversification in fish.
What caused the increase of carbon dioxide in the Permian-Triassic extinction event? They associate this anoxia with the prolonged eruption of the Siberian flood basalts (the so-called Siberian Traps), which probably led to higher levels of carbon dioxide in the atmosphere.

In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
Are turkeys close to extinction?
The truth is, turkeys are not an endangered species. If they were endangered and fell under Appendix 1 of the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), their trade would be forbidden and grocery stores could not sell them.
Can humans survive the Permian?
We would be restricted to pine nuts and a few edible tubers. Most of our diet would probably consist of insects, but 90 per cent of all insects at the start of the Permian were varieties of cockroach, so that’s hardly an attractive prospect. More importantly, we would still need to worry about being eaten ourselves.

What is the tree of life based on?
The tree of life is a metaphor which expresses the idea that all life is related by common descent. Charles Darwin was the first to use this metaphor in modern biology. It had been used many times before for other purposes. The evolutionary tree shows the relationships among various biological groups.
