There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

More like 100,000...

No, i don't think they'll need that much time.
You already see it now, their small ears, large skulls, dense orbital area, webbed toes, long, articulating spines, etc.
They've already begun the transition to a water dominate animal... 

Why? Hadn't they already been there for many thousands years?.. Did said changes appear in them over past century only & weren't noted in Pantanal Jags before that?
I'm not sure how long they've been there for but the pantanal has extreme conditions which is why you see distinguishable differences between them and their neighbors in the amazon.
And with the increase in Caiman over recent years it seems to be expediting that evolutionary process.
Their prey is limited there, especially in the north and I think that is why they've adapted quickly to adjust for their Caiman rich diet.

It's worth mentioning that unlike the lion, leopard and tiger, the jaguar is believed to be a monotypic species, meaning that it has no subspecies, despite the physical and geographical differences between different populations, like the Pantanal and Mexican jaguars: https://onlinelibrary.wiley.com/doi/abs/...0.CO%3B2-E
