Question

what important idea did jean - baptiste lamarck introduce that was not addressed by carolus linnaeus’s system?
an explanation for how species might change over many generations.
a system for giving every organism a unique scientific name.
the concept that organisms share certain characteristics.
a method for organizing organisms into different groups

Explanation:

Jean - Baptiste Lamarck introduced the idea of evolution, specifically that species might change over many generations (the first option). Carolus Linnaeus's system was about naming and classifying organisms, not about species change over time. So the important idea Lamarck introduced that Linnaeus's system didn't address is the explanation for how species might change over many generations.

The first option: An explanation for how species might change over many generations.
