Temperature spectrum of life

I have recently received communication of a new manuscript appeared in PLOS One, "The Biokinetic Spectrum for Temperature" by R. Corkrey and coworkers at the Univ. of Tasmania [see here]. The authors reconstructed the spectrum of temperatures where living organisms thrive, better, and more precisely, the authors reconstructed the distribution of temperature-dependent specific growth rate for life on Earth. The distribution shows a first peak centred at about 40 °C followed by a second one at higher temperature, 67 °C. Between the two peaks, a gap mirroring the separation between mesophilic and thermophilic species. The authors relate the biokinetic spectrum to the thermal stability of the underlying molecular machinery (proteins) sustaining the organisms metabolism. This is an intriguing contribution to understand the relationship among protein evolution and life adaptation in different thermodynamic environment. Enjoy it.
