Question

Use the Internet to trace the evolutionary stages of any one animal, e.g., panther. Discuss your research with your teacher and classmates.

Answer 1

• Miacis (about 55–50 million years ago): It was a small, weasel-like early carnivoran that represents an early stage in the evolution of modern carnivorous mammals.
• Proailurus (about 30 million years ago): It is considered one of the earliest known true cats, which was mainly tree-dwelling and possessed sharp claws and teeth.
• Pseudaelurus (about 20 million years ago): It was an early feline that played an important role in the evolutionary history of modern cats.
• Pantherine Lineage Split (about 10.8–11 million years ago): The ancestors of the big-cat group (Pantherinae) diverged from the lineage leading to smaller cats (Felinae).
• Panthera blytheae (about 4–6 million years ago): This fossil from Tibet is one of the oldest known fossils of the big-cat lineage, providing important evidence about the early evolution of Pantherinae.
• Modern Panthera (Present): The genus Panthera includes modern big cats such as the leopard, jaguar, lion, tiger, and snow leopard.
