All of today’s big cat species evolved less than 11 million years ago and yet their evolutionary history remains an almost total mystery. But scientists have recently discovered a major clue about the origins of the big cats, one that could provide a whole new starting place for solving this puzzle.

@Thunderblock7889 2 года назад

Some scentists suggest that the ability to roar was developed by lineages related to Panthera Leo and was passed upon other Panthera cats via crossbreeding. For instance its said that Lions crossbreed with Jaguars and Snow Leopards during the Pleistocene. This would explain with Jaguars can roar and Leopards cant despite Leopars bring more related to Lions than Jaguars are.

@sabbytheslothcat6663 3 года назад

@syedshakaibanwar2698 3 года назад

Biggest difference between Pantherinae and Sabertoothed cats such as Smilodons and Homotheriums is that Pantherine genus cats are called "Biting Cats" referring to their behavior of very often using their jaws, it's a bit too cheesy but basically Smiliodons didn't really have strong bites, if they were to inflict even the bit force of a Lion, their canines would shatter and they can't take a lot of stress either, they would break by being swatted at by a prey or other smiliodons, hence it is believed that they instead used their teeth in special ways such as cutting open a prey's soft portions with their canines. For Pantherines, they may be called Biting Cats but that behavior is also often seen in Cougars, although probably an example of convergent evolution.

@@abdulkarimismail9413 As others have said unfortunately flying animals don't typically fossilize well since the adaptations that make animals well adapted for flight make fossilization quite rare. The same is true of Insects Birds and the extinct Pterosaurs it is vary rare to find well fossilized specimens. The only conditions that seem to really make preservation of small flying animals likely is pyroclastic ash and anoxic waters as those both remove pretty much all risk of scavenging. Short of finding bat fossils in similar environments we don't really have much if any window into bat evolution. Add to that that Mammals are particularly known for having spotty fossil records and it becomes less likely for good fossilization to preserve bats.

@Just your friendly neighborhood quiet kid There are about six genera of well-preserved ancient bats (Onychonycteris, Icaronycteris, Archaeonycteris, Hassianycteris, Palaeochiropteryx, and Tachypteron) and they are actually all from lake environments. The first two are from the Green River Formation in Wyoming (about 52 million years old) and the last four are from the Messel Oil Shale in Germany (about 48 million years old). Messel actually preserves a lot of individuals--bats are the most common mammals there. But yeah, like others have said, there aren't any transitional bats and we don't even know what group of living mammals they are most closely related to.

PLEASE do an episode about the “so-called” American Lion!! I volunteer at a small museum with an Ice Age cave on grounds (Riverbluff Cave) which has trace evidence of an American Lion. I did not know that there was any controversy about the species, and I want to be up to date on my info, so I can give the most accurate tours possible! (And maybe some research?) Also, I have been *obsessed* with big, small, and domestic cats since childhood. I MUST KNOW!!!!

Well, logically it does make a lot of sense if the big cats evolved in southern Asia. After all, India is home to four of the five big cats - tiger, lion, leopard and snow leopard - as well as Panthera's closest living relative the clouded leopard. While Africa only has two Panthera species.

They're part of a stem split group in the lineage that leads to falcons and modern perching birds like crows and sparrows. Their notable intelligence is probably quite old, judging by comparable intellect that has been recorded in perching birds.

This comes as a surprise. Apparently the closest living relatives of tigers are snow leopards: ========== Tigers are less closely related to lions, leopards and jaguars than these other big cats are to each other, according to a new comprehensive study. The genetic analysis also reveals the tiger began evolving 3.2 million years ago, and its closest living relative is the equally endangered snow leopard. bigcatrescue.org/tigers-evolved-with-snow-leopards-gene-study-reveals/?amp

@Dragrath1 5 лет назад

@@TheZenytram The ability to breed says more about the chromosomal history of the animals and whether or not rearrangements have occurred within a lineage at only 11 million years old big cats are probably far too young to have acquired enough of those type of events to render offspring nonviable. The other equally if not more important information is whether or not the animals can mate in the wild and equally whether or not hybrid offspring can survive on their own. Take Carolina Chickadees and Black Capped Chickadees both can successfully breed with each other but the hybrid offspring are just not able to compete with either of their parent species and thus don't get to pass on their genes. The effect is that while they can breed with each other the non-survival of hybrid offspring on their own can serve as just a powerful barrier. Alternatively though sometimes hybridization can result in a new species if there is an unoccupied niche.
