It’s the ability to pass behaviors, traditions, and knowledge to the next generation. Cultural transmission has likely been a feature of our direct-line hominin mind for millions of years. Returning to what we

30 Phil, Chapter 1 Touchstone 3: Evolution. In 1859, the naturalist Charles Darwin revolutionized the scientific world with his seminal publication, “On the Origin of Species.” In it he formulated his scientific theory of evolution by natural selection. The process by which new species arise is well-understood. It proposed that changes in species occur gradually over time. With each generation,
30 Phil, Chapter 1 Touchstone 2: Free Will. There are two basic types of Free Will. Determinism says everything that happens is set in stone and can’t be changed; in contrast, indeterminism says people and animals make choices. There are four basic types: scientific determinism, scientific indeterminism, fatalism, and providence.
The dawn of collective learning can be traced back the oldest known stone tools, discovered at Lomekwi 3 in Kenya. The creation of these tools required more than just individual innovation; it involved the rudimentary form of collective learning, where knowledge of toolmaking was shared within groups. This early transmission of skills not only enhanced

NSLCA: The Neanderthal-Sapien Last Common Ancestor was likely Homo heidelbergensis or Homo antecessor. Analysis: Before the discovery of Homo antecessor in the 1990s, Homo heidelbergensis was considered the primary candidate for the NSLCA due to its chronological and morphological position in the human lineage. The discovery of Homo antecessor, with its more modern-looking facial features, has

660,000 Generations Ago The Last Common Ancestor (LCA) of the Great Apes, a.k.a. the Hominidae family, marks a pivotal point in our evolutionary history, encompassing the origins of orangutans, gorillas, chimpanzees, and humans. This ancestor species, likely existing between 15 to 19 million years ago, represents the shared lineage from which all modern great apes

Likely white or grayish atmosphere: The first atmosphere developed first but was not directly involved in the development of life.

25,600 Generations Ago NSLCA Candidate: Homo heidelbergensis, an important figure in human evolution, represents a notable advancement over its predecessor, Homo erectus and Homo antecessor. Emerging around 640,000 years ago, they exhibited a larger brain capacity, averaging about 1,100 to 1,400 cubic centimeters, which facilitated more complex thought processes and behaviors. This increase in brain
