rising superstar: see his lecture; and look at publications per year... a dynamo.</p>
<p>
see his res interests:</p>
<p>
Cryogenian 850 to 635 Mya and Ediacaran 635-542.</p>
<p>
Summary of talk:
Predation takes oxygen; could not have macropredators without it;
he correlates incr oxgen with changes in iron content in strata that he studies in Yukon.
It also correlates with fauna.</p>
<p>
Size and complexity of fauna also correlates with what is now found in modern oceans
in OMZs = oxygen minimum zones as an analogue to ancient low O2 oceans.</p>
<p>
also looks at LCA = last comon ancestor from molec clock studies that he does:
LCA of humans and fruit flies = 670 Mya. (that is LCA of all bilaterians)</p>
