Biodiversity of Europe's mammals as rich as it was 8,000
years ago, according to new research
A new study comparing the biodiversity of wild mammals in
Europe 8,000 years ago with the present has found that more
species have been gained than lost on the continent.
The study, published in Global Change Biology and led by
the University of York, found that recent species recovery
and the introduction of non-native species has increased
diversity by equivalent or greater amounts in many European
regions, despite loss of habitat and local extinctions in
many areas.
. . .
So much for the "loss of biodiversity" myth ...
One thing goes, it creates a niche for something new.
What's interesting is how high the MUTATION rate must
be to support this rate of new species creation. Seems
"species" are rather unstable. The moment there's any
elbow-room they split into something different enough
to call a "species".
