INTRODUCTION THE land faunas of oceanic islands have always excited considerable evolutionary speculation, and, starting with the “Origin of Species”, the Geospizinæ, the endemic Galapagos finches, have probably featured in as many evolutionary discussions as any group of animals. They differ fro...
The number, chromosomal locations, regional clustering, and lack of overlap of epimutations and genetic mutations suggests that epigenetic changes are distinct and that they correlate with the evolutionary history of Darwin's finches. The potential functional significance of the epimutations was explored...

通过一个更久远的祖先,燕雀(finches)与麻雀(sparrows)、老鹰、企鹅和所有其他鸟类有关。此外,雀鸟和其他鸟类与我们有亲缘关系,通过更古老的共同祖先。追溯生命足够远,我们将抵达生活在地球35亿年前的早期原核生物。我们可以在我们自己的细胞中认出它们的痕迹,例如在通用的遗传密码中。事实上,所有的生命都通过其悠久...
In the finches that Darwin observed some had large beaks that could be used to eat large seeds. Others had thin, small, beaks that were good at picking up and eating small seeds. Some of the finches had even developed beaks that were adapted to catching insects. However, the fact ...

通过长时间在不同环境下,这些脊椎动物从一个共同祖先开始,往不同方向发展,这个过程叫adaptive radiation(As the limb structure changed as a response to different environments, this type of evolution is called adaptive radiation)。 另外一个例子是Galápagos Islands的雀鸟(finches)的嘴(beaks)。雀鸟的嘴是遗传...
Our results extend current understanding of the plasticity of the adaptive immune system and suggest an important role for immune-related genes in animal diversification.

When thinking about the evolution of a characteristic, it is probably best to think about the change of the average value of the characteristic in the population over time. For example, when natural selection leads to bill-size change in medium ground finches in the Galápagos, this does not ...
