					<description><![CDATA[The Origin of Life and Life on Other Planets Several parallel discussions inspire me to write this post partly in the hope that you will chime in. The chance of life elsewhere in the universe just went to near zero. Or did it?

					<description><![CDATA[The earliest life must have been something like a small single celled organism, like a bacterium. Or at least, the earliest life that we can usefully conceive of, and potentially connect with living life. It has been suggested that life could have initially evolved at the site of submarine hydrothermal vents, which is a place &#8230; <a href="https://gregladen.com/blog/2017/03/15/earliest-or-nearly-earliest-fossils-found-in-quebec/" class="more-link">Continue reading <span class="screen-reader-text">Earliest, or nearly earliest, fossils found in Quebec?</span> <span class="meta-nav">&#8594;</span></a>]]></description>

					<description><![CDATA[Over the last several months, a lot of great books on fossils and evolution (as in paleontology) have come out. I&#8217;ve selected the best for your consideration. These are great gifts for your favorite science-loving nephew, life science teaching cousin, or local school library. Actually, you might like some of these yourself.

					<description><![CDATA[Imagine a &#8220;primordial soup&#8221; on some planet somewhere from which there occasionally emerges a thing that could locomote, and as it locomoted around it would scrape up some of the dust that lay around on the planet, and occasionally eat other things that had come out of the &#8220;primordial soup&#8221; and it would thus grow. &#8230; <a href="https://gregladen.com/blog/2012/01/11/comments-on-zimmers-can-a-scie/" class="more-link">Continue reading <span class="screen-reader-text">Comments on Zimmer&#039;s &#34;Can A Scientist Define Life?</span> <span class="meta-nav">&#8594;</span></a>]]></description>

					<description><![CDATA[I heard it said recently that &#8220;Evolution&#8221; and &#8220;Origin of life&#8221; are two separate issues.

					<description><![CDATA[In his highly readable book, One Long Argument, Ernst Mayr breaks down the body of thought often referred to as &#8220;Darwin&#8217;s Theory&#8221; into five separate and distinct theories, the second of which being &#8220;common descent.&#8221; Darwin&#8217;s second evolutionary theory (second by Mayr&#8217;s count, not Darwin&#8217;s) is really a hypothesis that could be worded this way: &#8230; <a href="https://gregladen.com/blog/2010/12/02/nasas-new-organism-the-meaning/" class="more-link">Continue reading <span class="screen-reader-text">NASA&#8217;s new organism, the meaning of life, and Darwin&#8217;s Second Theory</span> <span class="meta-nav">&#8594;</span></a>]]></description>
