4-Cultural Age

Cultural Age (800,000 to 440,000 years ago): A time of rapid evolution of the brain (nature) and significant cultural advancements (nurture). A time of better constructed homes, better control of fire, and better communication including language.

Neanderthal-Sapien LCA

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

First Clothes: Proto-Clothing and the Advent of Garments

Proto-clothing, encompassing basic garments such as animal skins and possibly decorative natural materials, likely emerged among hominins around 600,000 years ago, with Homo heidelbergensis being a probable early adopter. This species, experiencing diverse and often colder climates across Europe and Africa, may have utilized simple clothing for survival. Before venturing into colder climates, modesty, jealousy,

Homo heidelbergensis

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

Hyoid Bone: Speach Emerges

Around 700,000 years ago, the development of a human-like hyoid bone suggests early hominins may have begun transitioning from simple vocalizations to more structured speech. This period marks a critical evolutionary point for Homo heidelbergensis, whose anatomical adaptations for speech, coupled with advanced tool use and complex social structures, indicate possible use of rudimentary language.
