Oct 21, 2024 · human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture -bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago. We are now the only living members of what many zoologists refer to ...

Jan 19, 2017 · Second, human activities can have strong effects on the evolution of particular ‘important’ species, which can then have cascading effects on the broader community . These cascading effects could be a direct result of trait change in the important species; that is, trait-mediated effects of an evolving species on the community in which it is embedded.

- 550,000 to 750,000 Years Ago: The Beginning of the Homo sapiens Lineage. Genes, rather than fossils, can help us chart the migrations, movements and evolution of our own species—and those we descended from or interbred with over the ages.
- 300,000 Years Ago: Fossils Found of Oldest Homo sapiens. As the physical remains of actual ancient people, fossils tell us most about what they were like in life.
- 300,000 Years Ago: Artifacts Show a Revolution in Tools. Our ancestors used stone tools as long as 3.3 million years ago and by 1.75 million years ago they’d adopted the Acheulean culture, a suite of chunky handaxes and other cutting implements that remained in vogue for nearly 1.5 million years.
- 100,000 to 210,000 Years Ago: Fossils Show Homo sapiens Lived Outside of Africa. Many genetic analyses tracing our roots back to Africa make it clear that Homo sapiens originated on that continent.
Mar 24, 2011 · Students can collect data assessing the level of anthropogenic change and discuss the impact that these human activities may have or have had on local species evolution and the ecosystem in general. Anthropogenic field trips bring a sense of authenticity to the educational experience by allowing students to experience first-hand the environmental degradation occurring where they live.

Aug 21, 2019 · Evolution is defined as descent with modification through the process of natural selection. Human evolution follows this scheme. Humans share a common ancestor with primates dating back approximately 6 to 8 million years; Homo sapiens, or modern humans, have been around for about 100,000 years.

Abstract. Humans have dramatic, diverse and far-reaching influences on the evolution of other organisms. Numerous examples of this human-induced contemporary evolution have been reported in a number of ‘contexts’, including hunting, harvesting, fishing, agriculture, medicine, climate change, pollution, eutrophication, urbanization, habitat ...
