All of these were confusing discoveries that called into question the concept that species didn't change. Isolated species that looked similar to species that lived considerable distances away suggested that maybe they had a common ancestor that evolved over time. Organisms that had some similar characteristics but other characteristics that were very different suggested that maybe they evolved from a common ancestor but adapted differently to their environment. Organisms with similar structures that have different functions suggested that maybe they evolved from a common ancestor but adapted their structures to serve different needs. And body parts with no apparent function suggested that maybe they were leftovers from an ancestor that had a use for that body part, but over time it became unnecessary. All of these discoveries challenged the idea that species were static and unchanging.
