Homo sapiens idaltu, also known as the Herto Man, is believed to be the direct ancestor of modern humans, based on fossil evidence found in Ethiopia.

Evolution refers to the process by which populations of organisms change over generations, resulting in the emergence of new species and the adaptation of existing ones to their environment.

Humans lack a prehensile tail, which is a grasping tail found in some primates like monkeys. Bipedalism, large brain size, and tool use are all distinctive human characteristics.

Natural selection is the driving force behind evolution, where individuals with traits that enhance their survival and reproduction have a higher chance of passing those traits to the next generation.

Cladistics is a method used to study evolutionary relationships by analyzing shared characteristics among different species and constructing branching diagrams called cladograms.

Pan troglodytes is the scientific name for chimpanzees, which are not hominins but belong to the family Hominidae along with humans.

Lucy is the nickname given to the fossil remains of Australopithecus afarensis, discovered in Ethiopia. It is one of the most significant hominin fossils, providing insights into early human evolution.

Pottery is not a hominin tool. It is a ceramic ware made by humans, typically used for storage or cooking, and is associated with later stages of human cultural development.

Hominid refers to all members of the family Hominidae, which includes humans, chimpanzees, bonobos, and extinct hominin species like Australopithecus and Homo erectus.

Multiregional Evolution is a theory that suggests that modern humans evolved from multiple hominin species through interbreeding and gene flow, rather than a single population in Africa.

Neanderthals had a prominent chin, unlike modern humans. They possessed a robust build, large brain size, and a prominent brow ridge.

Adaptation refers to the process by which a species gradually changes over time to become better suited to its environment, increasing its chances of survival and reproduction.

Lascaux Cave is famous for its prehistoric cave paintings but is not a hominin fossil site. Olduvai Gorge, Turkana Basin, and Denisova Cave are all significant hominin fossil sites.

Homo floresiensis, also known as the 'Hobbit', is a hominin species discovered in Indonesia. It is known for its small stature and unique features, including a small brain size and long arms.

Carnivory is not a typical hominin diet. Hominins are omnivores, meaning they consume both plant and animal matter. Hunting and gathering, scavenging, and agriculture are all common hominin dietary strategies.
