Calorie-Free Sweeteners. Stevia. Derived from the leaf of a South American shrub, this natural substance is up to 200 times as sweet as sugar. Stevia-based products like Truvia and Pure Via are made from a purified extract of the plant, called rebaudioside A (Reb A), and sugar alcohols.
The Cenozoic Era was the first era that saw humans evolve. Much of what the common population thinks of as evolution all happened in the Cenozoic Era. The first period of the Cenozoic Era is called the Tertiary Period.Recently, the Tertiary Period has been broken down into the Paleogene Period and Neogene Period.he modern human evolved and became the dominant species on Earth. Other mammals on Earth continued to diversify and branch off into various species. The same happened with marine species. There were a few extinctions over this time period as well, due to the changing climate.
The development of human characteristics took place over millions of years. The earliest primate (an order of mammals that includes humans, apes, and monkeys), no bigger than a rat, appeared 60 million years ago. About 10 million years ago, the Ramapithecus showed remarkable hominoid attributes. But there is no further evidence until 6 million years later. The first generally accepted hominoid is called Australopithecus, and some believe they are actually the most primitive of the human lineage. Homo habilis, dating back at least 2 million years in modern-day Africa, is undisputedly human.
