Cloning extinct species #2: Should we bother?

May 10, 2010

Two weeks ago I posted about how, theoretically at least, one could go about bringing an extinct species back to life by cloning.  Its clear that for long-extinct species like the mammoth, where only degraded remains are available, cloning is still a very long way off and in fact may not ever be possible.  But for species that have only recently gone extinct, or are on the verge of extinction, correct preservation of tissues could see clones created (in fact this has already happened in the case of the pyrenean ibex).  But should we bother going down this path?

Cloning extinct species #1: A how-to guide

April 30, 2010
 Fancy seeing herds of mammoths running across the tundra, moa crashing through the undergrowth, or perhaps a tasmanian tiger lurking in the Aussie bush? Well in the near future these images might not just be the stuff of far-fetched Hollywood movie plots.  Advances in molecular biology and genomics mean that the ability to clone extinct species is getting closer. In theory, at least.  In this post I’m going to look at how one would go about bringing back to life their favourite extinct species, and in a later post I’ll discuss whether we should bother.
