J: List the THREE characteristics of a species.

One key characteristic of a species is the ability to reproduce and produce viable offspring, ensuring the continuation of genetic traits. This reproductive isolation often means that members of different species cannot interbreed successfully, maintaining distinct species identities. Another important characteristic is a shared genetic makeup and common evolutionary history, which means individuals within a species share a significant amount of DNA. This shared heritage helps identify a species and connects members through evolutionary processes, highlighting their adaptation to environments over time.
