Language is the one thing that truly sets us apart from the rest of the animal kingdom. It has enabled us to adapt to new environments and situations much faster than evolution allows. Indeed, many aspects of language act in parallel with evolution. Since speech leaves no physical clues for archeologists to find, little is known regarding when and how we acquired it. Christine Kenneally explains the problem of exploring the advent of language in her book The First Word. She states, "For all its power to wound and seduce, speech is our most ephemeral creation; it is little more than air. It exits the body as a series of puffs and dissipates quickly into the atmosphere. ... there are no verbs preserved in amber, no ossified nouns, and no prehistorical shrieks forever spread-eagled in the lava that took them by surprise." Scientists have had a difficult time piecing together the story of how we developed language. This post will cover some of their findings.
Read MoreWe can produce glucose from the protein we ingest in the absence of fat and carbs in the diet. Making glucose from protein is a process known as gluconeogenesis. The problem is that our ability to synthesize glucose from protein is very limited and will not sustain us longterm. Luckily, we have such an abundance of food today, most people will never have to rely on gluconeogenesis, except for me. Today, I would like to share my story and put the knowledge I gained from my experience into the larger framework of human evolution and biology.
