Conclusions from the research paper ‘The origin of endothermy in synapsids and archosaurs and arms races in the Triassic’ suggest relatively very rapid evolution for creatures living, breeding and dying in planet Earth’s dielectric environments:
# Birds and mammals likely acquired endothermy (warm-bloodedness) at the same time.
# Life remodelled itself most significantly in the aftermath of the devastating end-Permian mass extinction.
# The switchover happened in parallel with a shift in posture from sprawling to parasagittal in both major lineages.
Ultra rapid or near instant evolution through changes in worldwide and local electromagnetic energies?
