Species-Time Hypothesis 

Communities diversify, that is, gain species, with time

Temperate regions are less species-rich than tropical regions because they are younger and have only more recently recovered from glaciations and severe climatic disruption

                                                                        Helix-turn-Helix

Two helices are connected by a small loop or turn

These helices are stabilized by non-polar contacts between the helices

Mostly found in DNA binding proteins, directly involved in DNA binding

Generally consists of 20 amino acids

Second helix is involved in DNA binding, enters in major groove of the target site

That time, there was no selective pressure for rubisco to discriminate between CO2 and O2. 

The Km for CO2 is about 9 microM, and that for O2 is about 350 microM. The modern atmosphere contains about 20% O2 and only 0.04% CO2, so an aqueous solution in equilibrium with air at room temperature contains about 250 microM O2 and 11 microM CO2—concentrations that allow significant O2 “fixation” by rubisco and thus a significant waste of energy.
