The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize (corn), wheat, rice, barley, and millet as well as forage, building materials (bamboo, thatch, straw) and fuel (ethanol).
At the time, paleoanthropologists took little notice of Verhoeven's claims or if they did, they discounted them outright.
Almost thirty years later, an Indonesian-Dutch research team uncovered evidence at the Soa Basin which confirmed Verhoeven's original findings.
How do scientists know how old an object or human remains are?
What methods do they use and how do these methods work?
The rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales.
based on the tribe Poeae described in 1814 by Robert Brown, and the type genus Poa described in 1753 by Carl Linnaeus.
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
It can be a form of courtship that consists of social activities done by the couple.
The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
