Walkman, if lots of people were writing about "Frog habitats in planet Jupiter" you'd only be #1 if you were offering a more insightful view or a more granular level of detail about Jupiter, the frogs in question and the challenges those frogs faced getting to and inhabiting the planet.

If you used content someone else produced first without adding anything to it to show your greater knowledge and understanding of the issues frogs face on Jupiter, you'll probably be Panda'd once the search volume and number of relevant sites becomes significant enough for Google to regulate it.
