Why do animals live so long? Wouldn’t it make more sense to die after mating early in life as to have more gene turnover?

Evolution does not work based on what "makes more sense". And generally, there is no great advantage to a "higher gene turn over". It is all about one generation successfully passing their genes along to make another generation.

The Short Answer

Evolution does not work based on what "makes more sense". And generally, there is no great advantage to a "higher gene turn over". It is all about one generation successfully passing their genes along to make another generation. The timeline, in general, is irrelevant. Some animals mature quickly, mate, and die early. Some animals live for a very long time. If both species are successful, then why should the timeline matter?
