[Taxacom] How old?

[John Grehan]

In relation to Ken's recent objections about gaps being too big, here's a
whoppa:

"Now, new research suggests the first land plants began taking root 500
million years ago, 100 million years earlier than scientists thought. Until
now, scientists used the oldest known land plant fossils, roughly 420
million years old, to date their arrival on Earth's continents. In the
latest study, scientists used molecular clock analysis to more accurately
pinpoint the origin of the earliest land plants.

So, these molecular theorists propose an origin that requires land plants
to have stuck around for at least 100 Ma with no fossil record.
