morning ponder
chicken little yelled "the sky is falling" all the time.
but before chicken little was his uncle, chicken large.
chicken large yelled "the sky is rising" all the time.
perspective
lowest and highest ocean level
elevation=gradient of oxygen density
population has preference for living near coast lines
speculation
as population moves toward lower elevations, size adaptations.. ie larger
would 'splain giants/bigfeets dagnersaurs etc
