The Origins of Big Cats: Discovering their Mysterious Heritage

🐯The big cat lineage originated in central-northern Asia around 10.72 million years ago, challenging the previous belief that they evolved in Africa.

🌍Big cats rapidly diversified over the next 8 million years, first in central-northern Asia and later in Africa and North America.

🔬Fossil evidence for the ancestors of big cats is scarce, leading to their classification as a ghost lineage.

🧬Genetic analyses provide additional insights into the evolutionary history of big cats, filling in gaps in the fossil record.

❓The discovery of fossils in the Himalayas has opened up new possibilities for understanding the origins of big cats.

Where do big cats originate from?

—Recent discoveries suggest that big cats originated in central-northern Asia around 10.72 million years ago, challenging the previous belief that they evolved in Africa.

What is a ghost lineage?

—A ghost lineage refers to the ancestors of a species that are known to exist but have limited or no fossil evidence to illustrate their lineage.

How do genetic analyses contribute to understanding the origins of big cats?

—Genetic analyses provide additional insights into the evolutionary history of big cats by filling in gaps in the fossil record.

Why is there a significant gap in the fossil record for big cats?

—The behavior of big cats, such as living alone or in small groups and having large territories, along with the similarity of their skeletons, makes it challenging to find and identify their fossils.

What did recent discoveries in the Himalayas reveal about the origins of big cats?

—The discovery of fossils in the Himalayas suggests that big cats originated in central-northern Asia, providing new insights into their evolutionary history.
