Oldest miniaturized stone toolkits in Eurasia

Microliths are often interpreted as being part of composite tools, including projectile weapons, essential to efficient Homo sapiens hunting strategies. In Europe and Africa, these lithic toolkits are linked to hunting medium and large-sized animals in grassland or woodland settings, or as adaptations during periods of climatic change. The presence of microliths in Sri Lanka suggests the existence of more diverse ecological contexts for these technologies by some of the earliest members of our species.

Understanding the causes and consequences of Late Quaternary megafaunal extinctions is increasingly important in a world of growing human populations and climate change. A review highlights the role that cutting-edge scientific methods can play in broadening the discussions about megafaunal extinction and enabling insights into ecosystems and species-specific responses to climate change and human activities.

Why are there no animal species with three legs?

If 'Why?' is the first question in science, 'Why not?' must be a close second. Sometimes it's worth thinking about why something does not exist. Such as a truly three-legged animal. At least one researcher has been pondering the non-existence of tripeds.

250-million-year-old evolutionary remnants seen in muscles of human embryos

October 1, 2019 0 Comments Biotechnology, Charles Darwin, Developmental Biology, Early Humans, Evolution, Evolutionary Biology, Human Evolution, Nature

A team of evolutionary biologists have demonstrated that some limb muscles known to be present in many mammals but absent in the adult human are actually formed during early human development and then lost prior to birth. These findings offer insight into how our arms and legs evolved from our mammalian ancestors, and also help explain rare limb anomalies found in humans born with congenital malformations.

Scientists have shown for the first time that cooking food fundamentally alters the microbiomes of both mice and humans, a finding with implications both for optimizing our microbial health and for understanding how cooking may have altered the evolution of the our microbiomes during human prehistory.

Insight into competitive advantage of modern humans over Neanderthals

A team of researchers have evidenced mechanically delivered projectile weapons in Europe dating to 45,000-40,000 years — more than 20,000 years than previously thought. This study indicated that the spear-thrower and bow-and-arrow technologies allowed modern humans to hunt more successfully than Neanderthals — giving them a competitive advantage. This discovery offered important insight to understand the reasons for the replacement of Neanderthals by modern humans.

Etched onto the steep walls of Arizona's 6,000-foot-deep, 277-mile-long Grand Canyon are clues that chronicle the sweeping changes the region has experienced during the past two billion years. The canyon's colorful layers narrate tales of ancient environments come and gone, from lofty mountain ranges and tropical seas to a Saharan-scale desert that once stretched across much of western North America.
