isPermaLink="false">http://biology-today.com/?p=1488</guid> <description><![CDATA[In 1908, English mathematician Godfrey H. Hardy and German physician Wilhelm Weinberg independently derived a mathematical model describing what happens to the frequency of alleles in a population over time. Their combined ideas became known as the Hardy-Weinberg theorem. It states that the mixing of alleles at meiosis and their subsequent recombination do not alter [...]]]></description> <wfw:commentRss>http://biology-today.com/evolution/what-is-hardy-weinberg-theorem/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Lamarckism</title><link>http://biology-today.com/evolution/lamarckism/</link> <comments>http://biology-today.com/evolution/lamarckism/#comments</comments> <pubDate>Fri, 18 Sep 2009 16:09:50 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Evolution]]></category> <category><![CDATA[lamarckism]]></category> <category><![CDATA[theory]]></category><guid

It was published in 'Philosphie Zoologique' in the year 1809. It is popularly known as "The Inheritance of Acquired Characters in Organisms'.

But an absolute proof in this connection is lacking. The circumstantial proof is the only type of evidence available.

isPermaLink="false">http://biology-today.com/?p=535</guid> <description><![CDATA[The similarities among living organisms indicate that all of them have evolved from some single common ancestor (This is called monophyletic origin). Through the process of gradual modifications, adaptations and natural selection, over a million and a half different species have evolved from a common ancestral form. This process is called evolution or organic evolution.

These fluctuations constitute genetic drift or Sewall Wright effect. The potential role of drift in microevolution is considerable. Dunker religious community in Pennsylvania (U.S.A.) comprises a small population.

In case of the evolution of many organisms one or more stages of the sequence are yet to be discovered. These stages were constituted by such organisms which connected two large and distinct groups of organisms.
