Have you chosen a purpose that is worthy of your best efforts?

As will be explored in this essay, all of the marine life have anoxia as a suspected contributing cause, so oxygen is a major area of interest among extinction specialists. Whether oxygen levels were also significant contributing causes of evolutionary innovation is another area of interest today. Again, to food chains. Even if the first animals did not respire anaerobically, they adapted to aerobic respiration early on and then became dependent on it. There would be no going back for animals; all except those few adapted to and anoxic environments went “all in” with aerobic respiration.

We can correctly conclude that the purpose for our existence is to.

What could make the purpose of life worth living.

Many observable common aspects of today’s simians probably reflect ancestral traits predating the evolutionary splits that led to humans. A chimpanzee’s brain is about 360 cubic centimeters (“ccs”) in size, and that gracile australopithecine that probably had a brain of about 450 ccs. That brain growth reflected millions of years of evolution since the chimpanzee line split, at least a million years of bipedal existence, and . The cognitive and manipulative abilities of the species that made early stone tools seem to have been significantly advanced over chimps.

Other than humans, rhesus macaques are Earth’s most widespread primates, and both species are generalists whose ability to adapt has been responsible for their success. Rhesus macaques are , about twice that of dogs and cats, and nearly as much as chimpanzees. Rhesus macaques have what is called Machiavellian social organization, in which everybody is continually vying for rank and power is everything. Those with rhesus power get the most and best food, the best and safest sleeping places, mating privileges, the nicest environments to live in, and endless grooming by subordinates, whom the dominants can beat and harass whenever they want, while those low in the hierarchies get the scraps and are usually the first to succumb to the vagaries of rhesus life, including predation. It is the . But even the lowliest macaque will become patriotic cannon fodder if his society faces an external threat, as even a macaque knows that a miserable life is better than no life at all. The violence inflicted seems economically optimized; within a society the violence is mostly harassment, but when rival societies first come in contact, the violence is often lethal, as the initially established dominance can last for lifetimes. Within a society, killing a subordinate does not make economic sense, as that subordinate supports the hierarchy. Potentates rely on slaves. The human smile evolved from the teeth-baring display of monkeys that connotes fear or submission.

Most of us can quickly tell what the purpose is for mosteverything with which we come into contact.
The public schools fail to teach us a legitimate purpose for our existence.

In 1972, Niles Eldridge and Stephen Jay Gould published their theory of , which has . The basic idea is that species usually evolve slowly and even remain in a kind of stasis, except in exceptional times, when they can evolve relatively quickly. Those exceptional times are often when new ecological niches become available, such as a new biological feature that allows exploitation of previously unavailable niches, or after an ecosystem is wiped clean by a mass extinction. If a creature finds a way of life that works and it can keep exploiting/defending its unique niche, and the niche does not disappear, it can keep doing it for hundreds of millions of years without any significant changes, such as the , , and have done.

So, let's examine a few ideas from the Bible that will help us discover our purpose forexistence.

Those issues will not be resolved in my lifetime, but migrated past Africa in the . There is evidence and speculation that those humans may have bred with Neanderthals, were killed off by them, migrated across Eurasia, or some combination of those events. There is evidence that or Neanderthal descendants, the , also migrated across Eurasia, perhaps expanding to Southeast Asia as did. The Denisovan evidence arose from analyzing DNA from teeth and bones, which is the only physical evidence of Denisovans discovered so far, and their genes are more prevalent in . To summarize, there is substantial evidence that the human line probably populated Eurasia in significant numbers by 200 kya, and perhaps even anatomically modern humans around 100 kya. They could have driven vulnerable species to extinction, with their advanced toolkit and hunting behaviors, long before behaviorally modern humans left Africa about 60-50 kya. became extinct in East Asia or the islands off of it, and the . Those two primates coexisted for more than a million years and disappeared concurrent with the rise of humans with sophisticated toolsets. They may well have been early casualties of humanity’s success.

Or perhaps it is the unsureness of the life after death that may make one cling to their being.

What is the purpose of my existence

The derision was loud from Wrangham’s colleagues…until evidence of was found at in South Africa by using new tools and techniques. The chortling is subsiding somewhat and scientists are now looking for the faint evidence, and long-disputed evidence of 1.5-1.7 mya controlled fires is being reconsidered, although his hypothesis is still widely considered as being only "mildly compelling" at best. New tools may push back the control of fire to a time that matches Wrangham’s audacious hypothesis. Wrangham cited the Expensive-Tissue Hypothesis as partially supporting the Cooking Hypothesis, but , the energy to power the human brain may not have solely derived from cooked food’s energy benefits. Wrangham has cited numerous lines of evidence, one of which is a that has to find honeybee hives and smoke them out; the humans get the honey and the honeyguide gets the larvae and wax. According to recent molecular evidence, the evolutionary split of the honeyguide from its ancestors happened up to three mya, which supports the early-control-of-fire hypothesis. There is great controversy regarding these subjects, from recent findings that to scientists making arguments that to the social impacts of campfires. This section of this essay will probably be one of the first to be revised in future versions, as new evidence is adduced and new hypotheses are proposed.
