Evolving, but how. I believe Darwin’s capabilities are vastly overrated today.
Most evolution occurs in times of stress, immediately after changes.
In fat years, everyone survives, and variations can accumulate.
In lean years, selection occurs.
At Pt. Mugu, during WWII a small creek was used as the source of dirt to build the foundation for a runway. The hole created left a tidal estuary. Brackish water enters, and exits, diluted by the fresh water from the creek.
40 species of brine shrimp have evolved there since WWII, each selected for its own range of salinity and current. These species exist nowhere else in the world.
Where a species is fit for its niche, there little pressure for change. Where the environment changes, there is significant pressure for change.
New species are indeed evolving.
