Summary:The world is a big place – 7.4 billion people and counting. As much as we all enjoy the game of finding our doppelganger in a crowd, there probably isn’t anyone in the world who is exactly like us. With a genetic code of over 3 billion base pairs, of which there are innumerable permutations, we would be hard pressed to find a clone of ourselves even if the world had 7 trillion people. The exception is if you were born with an identical sibling. But then again, you would know if you had a twin. Wouldn’t you?
Summary:What is an atlas? To most people, an atlas is a collection of maps constructed by cartographers who meticulously plot the surface of the earth, inch by inch. In the medical field, we use the word atlas to refer to textbooks of human anatomy, but the endeavor is much the same, and no less painstaking – the human body is quite complex, after all. Though some anatomy atlases are famous for their beautiful depictions of anatomical structures, it is more important that they are accurate. What good would a map be otherwise?
Summary:Most students of biology are well aware of our humble beginnings as puny, single-celled lifeforms. The mechanism of our remarkable transformation was famously described by Charles Darwin in his groundbreaking text On the Origin of Species, published in 1859. In many respects, Darwin’s magnum opus was just the opening chapter of a much broader discussion of how we humans have taken our current form. Darwin elucidated only a general process of adaptation and evolution in the face of environmental pressures. He left his successors with the more onerous task of applying this rule to the tortuous history of human evolution.
“the history of living organisms has been shaped at every turn by earth’s vicissitudes, because every geologic upheaval, by causing profound changes in the distribution of land and sea, has had profound effects on the climates of both, and hence of the patterns of life in both” (pp. 9).By the final chapter, “Consciousness”, he has begun to ponder questions of metacognition and learning. He marvels at how our complex nervous system has allowed classical pianists to balance the rigidity required for technical prowess, and the fluidity required for creativity. This is not a textbook about our kidneys. From Fish to Philosopher is a story of mankind’s genesis, told through the existential musings of a physiologist who left no stone unturned.
Summary:Leonardo da Vinci – the name alone evokes images of an artistic virtuoso, the Renaissance man, the mind behind the Mona Lisa. Though known best as an artist, his work extended beyond paintings into a myriad of disciplines, with notebook entries documenting his studies of optics, bird flight, comparative anatomy, hydraulics, and countless others. And yet what has been obscured by the shadow cast by his prolific career are the details of how a young man from a town called Vinci became Leonardo da Vinci. What did he do every day? What did he eat? Who were his friends? Did he even have any? We tend to immortalize Leonardo as a god, and yet he was human after all, not unlike the rest of us. This realization should encourage us to study one of history’s most celebrated humans, and see if we ourselves might be able unlock our own inner genius.
