/ 100
True
Sharks appeared over 400 million years ago, while trees became common around 350 million years ago, making sharks older than trees.
Infact verdict: True (88/100).
The claims regarding the age of sharks and trees are supported by multiple reliable sources. Sharks are confirmed to have appeared around 450 million years ago, while trees became common approximately 350 million years ago. This makes sharks older than trees, as corroborated by sources like Smithsonian Magazine and the Natural History Museum. The evidence is consistent and comes from authoritative sources, leading to a high confidence in the factual accuracy of these claims.
