Global Ecology and Biogeography, Volume 31, Issue 9, Page 1810-1823, September 2022., 2022 Abstract Aim Human activities are causing massive increases in extinction rates but might also lead to drastic increases in speciation rates; for example, after human‐mediated spread of species to otherwise unreachable landmasses. The long‐term net anthropogenic effects on biodiversity therefore remain uncertain.

The Miocene: The Future of the Past
Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021 Abstract The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the same taxa that exist today.
