For the hominid lineage – all of our ancestors since our split with the chimpanzee/bonobo lineage – the fossil evidence for the human-chimpanzee last common ancestor (LCA) is scarce because: 1. Apes were extremely rare during the Miocene. 2. These apes lived in a narrow range of environments that were not preserved well in the fossil record (like forests). 3. The LCA lived in the Paleocene, a time from which we have essentially no fossil record. 4. Most of the primates known from the mid-Miocene are Old World monkeys, who are from a different Linnaean family than we are.

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
