Excuse me. Mixed in age: 1.76 mya is over 300,000 years earlier than other Acheulian finds. I believe the abstract itself mentions hypothesis of brain evolution leading to the more refined tool flaking. What i thought more interesting and also appropriate to questions of cultural versus...

Thank you for the delightful commentary! I'd like to note that many species communicate through context-dependent signals, one signal having different meanings in different social or activity-based situations. Only a minority of social communication is transmitted through verbal language...

Coevolution is the term used to describe the accelerated one-upsmanship of symbiotes. Ecosystems - the habitats or environments - are observed as changing at different rates in response to changes in species and populations, as well as other factors, including nonbiological, involved in the...

Well, Ryan M B, Eldridge is still kicking, by the way. The fossil record consistently shows us that his and Gould's early '70s paper could accurately depict speciation: Period boundaries in geology are associated with sudden huge changes in the fossil record. However, across the earth, we do...

Cultural evolution, of course, occurs at even faster rates. Cultural evolution can be practically defined as changes in technology. It is Lamarckian! Evidence and analogue is everywhere in our own society, from internal combustion engines to computers and the powerful changes occurring...

Advanced evolution, or accelerated evolution - genetic and protein changes in the brain or in developmental processes, might not be the only explanatory hypothesis for clusters of paleontological findings. Let's look at the period mentioned by Haroldingo: About 50,000 years ago there seems to...
