The human body is a testament to millions of years of evolution, with each anatomical feature telling a unique story of adaptation and survival. One area of particular interest for researchers is the human shoulder and elbow joints, which have undergone significant changes throughout our evolutionary history. A recent study published in the journal Nature Communications1 sheds light on how these crucial joints evolved, hinting at our ancestors' climbing past. The study, conducted by a team of researchers led by Dr. Emma Nelson from the University of Liverpool, delved into the genetic and biome ..read more

1y ago
The study, which was published in Science Advances1, is based on fresh examinations of stone tools used by long-tailed macaques in Thailand's Phang Nga National Park. These monkeys break open nuts with the use of stone tools. The monkeys frequently smash their anvils and hammerstones in the process. The resulting collection of broken stones is sizable and dispersed throughout the countryside. Furthermore, many of these artifacts share the same traits with the stone tools that are frequently used to date some of the earliest archaeological sites in East Africa. Understanding how and when homini ..read more

Cashew nuts, West Indian locust seed pods, jatobá in Brazil, and other hard foods are cracked open using stones by Capuchin monkeys in the Cerrado and Caatinga as hammers and anvils. The instruments are bits of quartzite and sandstone discovered in locations known as processing sites. The only reason the animals visit these locations is to search for these stones to use as hammers and anvils. A nut or seed is pounded between two stones, one of which serves as an anvil. In a new study, Brazilian researchers demonstrate that the correlation between food hardness and tool size is not always as st ..read more

We are aware that many gorillas and chimpanzees are ferociously territorial. Both species will protect their home ranges against invading tribes. Members of other groups that intrude into chimpanzee territory are often killed. Furthermore, researchers discovered that a troop of chimpanzees in Gabon had killed newborn gorillas between 2014 and 2018 and even observed a mother chimpanzee eating an infant gorilla. With the aid of more than 20 years of data from the Nouabalé-Ndoki National Park in the Republic of Congo, the first study1 of its sort was able to see such long-lasting, peaceful relati ..read more

Humans & Chimpanzees Both Have A Propensity To Time Our Steps To Those Of Others

Much less is known about chimpanzees' inclination to coordinate spontaneously than about how they cooperate when working toward a goal, such tugging a string to release food. Chimpanzees and humans also inadvertently coordinate their movements when walking next to other members of their own species, according to a recent observational research1. According to the authors, this is an inherited trait. Chimpanzees walking together. Two adult male chimpanzees walking behind each other. Male and female chimpanzees of various ages, some related and some not, were used in the study. When the chimpan ..read more

Lemurs & Monkeys Are Descending From Trees As The Environment Warms

1y ago
A study1 based on some more than 150,000 hours of observations of 47 species of tree-dwelling primates spread across nearly 70 sites in Madagascar and the Americas led to the release of the warning that monkey and lemur species that live in trees are spending more time on the forest floor as a result of the temperature increase. Specifically, in locations where their forest is damaged and fragmented, some primates, such as howler monkeys and bamboo lemurs are expending more time on the ground. These primates are fighting for survival in forests ravaged by human activity and climate change, acc ..read more

by Kambiz Kamrani
1y ago
Researchers have found social bonds between specific chimpanzees and gorillas that endured over years and in many circumstances at Nouabalé-Ndoki National Park in the Republic of Congo. These observations span more than 20 years. The bulk of the remaining wild gorillas and chimpanzees live in close proximity, something most people are unaware of. Few studies of interactions between primate species have been able to account for inter-species relationships in the wild, but it is well known that these primates can recognize individuals within their own species and establish enduring connections ..read more
