How To Identify Plants At The Santa Rosa Plateau: Plant Evolution

• Imagine beginning with a single plant species at one moment in time. At first, there is just a range of variation in a single species.

• In time, that single plant species begins to differentiate, usually at the edges of its spatial distribution.

• Eventually, they become two almost-separate species that are hard to differentiate.

• Finally, they become two clearly-separate species.

• At any given moment in time, some plant species are in each of these stages!
