copy

Did this man, Erling Haaland, copy you with his Birkin obsession?

No, I don't think he copied me.

And I basically copied him, but I turned from looking for radio signals with an intelligent message to looking for signs of life by way of biosignature gases in a planet atmosphere far away.

The phrase "survival of the fittest'' stands for the process within a population, where fit variants leave reproductive copies of themselves and less fit variants reproduce less or disappear.
