What other animals have flip-flopped like this?
>>17076104dolphins. they're fucking retarded lol
>>17076106this true of all whales, but they didnt come back on land as far as we know
>>17076109they developed in water, managed to get on land, they noped back into the water. that's gotta sting now
>>17076111if you add "managed to get back on land yet another time" to that it would apply to turtles.
>>17076116they can't seem to make up their minds, like women
>>17076118anon please dont touch that turtle

>>17076160Dougal Dixon may have been a zoological shitposter, but there was a kernel of truth about his form/function filling theory about ecological niches
>>17076165I don't know who that is but are you familiar with Tenrecs? Technically they're related to Elephants.
>>17076182https://en.wikipedia.org/wiki/Dougal_DixonI will look up to Tenrecs
>>17076196>I will look up to Tenrecshow short are you?
>What other animals have flip-flopped like this?All venomous reptiles form a single monophyletic clade, despite many non-venomous reptiles being in that clade and them having numerous completely unrelated venoms across the group.Unless it's a ratite situation where they all just coincidentally have a propensity for developing venom and just did it a bunch of times across the clade, it's likely there's been a lot of flipflopping.Also non-zero chance mosasaurs were venomous.
>>17076472>Also non-zero chance mosasaurs were venomous.why in the world would they need to be?
>>17076104no one mentioned snails, so I will>originally marine gastropods>adapt to life on land>later on various lineages readapt to life in freshwater like streams, lakes, caves>some of those later spawn terrestrial species again
>>17076552>why in the world would they need to be?I dunno. Why do iguanas need to be?
>>17076552not everything happens on a need basis. if it's not expensive it can stay, if it ever pops up by chance
>>17076655do marine iguanas count?
