One such exercise involves students observing organisms (either live organisms, bones, or other preserved remains) and testing hypotheses about the evolutionary relationships of the species (Singer et al. 2001).
The symptoms usually manifest in situations of increased energy demand such as fasting, infectious illnesses, and intensive or prolonged physical exercise when the organism relies on fatty acid β-oxidation for energy supply.
While these are valuable teaching materials, inquiry based exercises that utilize living organisms can be more transparent, and offer a direct connection to the ecological theater in which evolutionary processes play out (Delpech 2009; Green et al. 2011; Olson and Loucks-Horsley 2000; Plunkett and Yampolsky 2010).
This exercise showed students the diversity of organisms found in the natural world as well as ways to map the relationships between organisms using phylogenetic trees.
Induction of mitochondrial biogenesis by CR or exercise has been shown in different organisms and tissues [33] [35].
The same perspective-shifting exercise could be applied to any organism on the tree of life, including chimpanzees.
We do realize the complexity of this issue and the necessity of exercising caution when applying models across organisms without knowing the full characterization of the deleterious outcome.
Such an exercise could start with a series of organisms and a tree for which parsimonious morphological phylogeny appears to be accurate, but is not supported by molecular characters (nucleotide or amino acid characters).
The exercise presented here leverages the genetic model organism Drosophila simulans and allows students to witness evolution in their own classroom at the phenotypic and molecular levels.
The lactate clamp method at rest is an appropriate method to examine physiological responses of lactate on the human organism without the effects of exercise.
