The earliest known piece of pewter was found in an Egyptian tomb, c. 1450 BC, [5] but it is unlikely that this was the first use of the material. Pewter was used for decorative metal items and tableware in ancient times by the Egyptians and later the Romans, and came into extensive use in Europe from the Middle Ages [ 6 ] until the various ...
Roswell Gleason (April 6, 1799 – January 27, 1887) was an American manufacturer and entrepreneur who rose from apprentice tinsmith to owner of a large manufacturing concern that initially produced pewter objects for domestic and religious use, and later added Britannia ware and silver-plated goods to its catalog.
The term "gender reveal" is considered a misnomer by those who believe in a distinction between sex and gender. [2] In this view, gender is a social construct and impossible to determine from biological characteristics. Thus, when the "gender reveal" is made, it is the sex and not the gender that is being revealed.
The last common ancestor between humans and other apes possibly had a similar method of locomotion. 12-8 Ma The clade currently represented by humans and the genus Pan (chimpanzees and bonobos) splits from the ancestors of the gorillas between c. 12 to 8 Ma. [31] 8-6 Ma Sahelanthropus tchadensis

Anatomically modern humans appear in Africa. [103] [104] [105] Around 50 ka they start colonising the other continents, replacing Neanderthals in Europe and other hominins in Asia. 70 ka Genetic bottleneck in humans (Toba catastrophe theory). 40 ka Last giant monitor lizards (Varanus priscus) die out. 35-25 ka Extinction of Neanderthals.
The linear view of human evolution began to be abandoned in the 1970s as different species of humans were discovered that made the linear concept increasingly unlikely. In the 21st century with the advent of molecular biology techniques and computerization, whole-genome sequencing of Neanderthal and human genome were performed, confirming ...
