LUCA was not pro-heat?

Fascinating study reported in Science Daily.

An evolutionary geneticist from the Université de Montréal plus with researchers from the French cities of Lyon and Montpellier published this study about the big daddy/mommy from whence all life on earth came from.

Ye, this common ancestor is referred to as LUCA (Last Universal Common Ancestor).

Read the article and related links of the site. For now, it is suffices to say that LUCA fella was not overtly fond of heat as was previously believed.

In fact, the study suggests that the organism might have found a cooler micro climate to go forth and prosper and all that.
