How Lions Evolved or Ghostly Origins of Big Cats

How Lions Evolved or Ghostly Origins of Big Cats

“All of today’s big cat species evolved less than 11 million years ago –just a blip in geologic time time”, yet their evolutionary tree and ancestry, remains as a mystery.
“Their ancestry is so hard for us to make out that it’s known as a ghost lineage. We simply don’t have enough fossils to understand their origins.”

How did lions evolve? The common ancestor of the Big Cats dates back 11 million years. But why is the evolutionary history of big cats a mystery?

Key Moments in Natural History

Key Moments in Natural History

This Earth is the home of creatures that have lived here for millions of years, some of them extant other extinct. The vast majority of our ancestors are extinct that is what evolution is about.

The key moments in the Natural History are the ones that shaped the future, that converted a mother nature possibility into a tangible reality.

Pre-Hominidae ancestry

So when appeared Purgatorius ceratops our common ancestor with other Hominidae?

“Around 65 million years ago, these little shrew-like creatures were climbing around in the threes of Western North America, munching on insect and fruit… But Purgatorius is was kind of mysterious because it didn’t have what we think as the classic primate traits, like forward facing eyes, or nails instead of claws.”

Purgatorius is a genus of six extinct eutherian species typically believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago.[1]

How Mosasaurus evolved?

If Mosasaurus disappeared totally or gradually, one thing is true the ocean has never seen again so giant reptiles dominating the aquatic world.

Never seen again a so powerful reptile ruling the oceans.

How butterflies evolved?

Butterfly Identifier iOS app

145 million years ago in the Cretaceous Period. “Butterflies have highly adapted hairs that contain colored pigment.” This help for camouflage, to confuse predators, for regulating temperature, and even for mating.

Learn how butterflies evolved. They have a singularity pattern found on its wings, a mathematical pattern that makes a specie unique among others.

When they appeared? How many families, genus, groups, species and subspecies of butterflies are extant, and who others are extint?

By the way I made an app for Butterfly Identification available on iOS here.

How evolution actually works?

How evolution actually works?

“The story of life on earth is a story of change. Living things have change the atmosphere and the climate. They’ve endure the movements of continents, and the rise and falls of the seas… Evolution. This powerful source is, in the simplest terms, just change over time.”

This force is the origin of the Tree of Life.

Organisms evolve over one principle: Natural Selection.
