<title>Protheros punctuated equilibrium</title>
<content:encoded><![CDATA[<p>&amp;quot;In four of the biggest climatic-vegetational events of the last 50 million years, the mammals and birds show no noticeable change in response to changing climates. No matter how many presentations I give where I show these data, no one (including myself) has a good explanation yet for such widespread stasis despite the obvious selective pressures of changing climate. Rather than answers, we have more questions&amp;#226;&amp;#128;&amp;#148;and that&amp;apos;s a good thing! Science advances when we discover what we don&amp;apos;t know, or we discover that simple answers we&amp;apos;d been following for years no longer work.&amp;quot;-http://www.skeptic.com/eskeptic/12-02-15/#feature-&amp;#13;&amp;#10;But human development continued following climate we think.</p>
