How long have penguins been on earth?

Penguins have existed on Earth for approximately 60 million years. Fossil records indicate the presence of penguins during the Paleocene era. The earliest known penguins were quite different from modern penguins and were characterized by beaks that were similar to those of modern puffins. Over time, penguins evolved and adapted to their unique marine environments, resulting in the various species we see today.
