Our closest biological relatives, the gorillas and chimpanzees and bonobos of Africa, also live in bands. All humans presumably did so too, until improved technology for extracting food allowed some hunter-gatherers to settle in permanent dwellings in some resource-rich areas. The band is the political, economic, and social organization that we inherited from our millions of years of evolutionary history. Our developments beyond it took place within the last few tens of thousands of years.
Infertility
Infertile means not able to have children or other offspring. Humans can be infertile, but animals and plants can too. When a human couple is infertile, they sometimes have fertility treatment to have children. This can be insemination or IVF. They also sometimes adopt a child.
Betrayal (disambiguation)
Betrayal can mean:
Betrayal
Betrayal is when a person breaks the trust and faith of others that trust them.
In an article made by Rodger L. Jackson, it says that "there is not much definition for this word". In psychology, they say betrayal is the breaking of a social (friendship) related things. But for some people, for example, philosophers called Judith Shklar and Peter Johnson, a person can understand the word better by literature (writings).
Betrayal trauma happens when someone that a person trusts betrays their trust, and it messes up their memory because of anger. An example of betrayal trauma is childhood physical or childhood problems. Betrayal trauma is similar to post traumatic stress disorder. The difference is that post traumatic stress disorder (PTSD) is made by fear. Betrayal trauma makes a person fight, and also get into serious crimes for example, discrimination or bullying.
Destruction
Destruction could mean:
Crane (machine)
A crane is a lifting machine that has hoists, wire ropes and sheaves on it. It can be used both to raise and lower things or to move them left and right. Cranes are often used in the construction industry (building houses or buildings) and in creating or moving heavy things.
Data mining
Data mining is a term from computer science. Sometimes it is also called knowledge discovery in databases (KDD). Data mining is about finding new information in a lot of data. The information obtained from data mining is hopefully both new and useful.
In many cases, data is stored so it can be used later. The data is saved with a goal. For example, a store wants to save what has been bought. They want to do this to know how much they should buy themselves, to have enough to sell later. Saving this information, makes a lot of data. The data is usually saved in a database. The reason why data is saved is called the first use.
Later, the same data can also be used to get other information that was not needed for the first use. The store might want to know now what kind of things people buy together when they buy at the store. (Many people who buy pasta also buy mushrooms for example.) That kind of information is in the data, and is useful, but was not the reason why the data was saved. This information is new and can be useful. It is a second use for the same data.
Finding new information that can also be useful from data, is called data mining.
For data, there a lot of different kinds of data mining for getting new information. Usually, prediction is involved. There is uncertainty in the predicted results. The following is based on the observation that there is a small green apple in which we can adjust our data in structural manner. Some of the kinds of data mining are:
Japanese sword-making
Japanese schools of sword making can be divided into two categories: by the provinces where they were developed and by the masters who created a specific tradition of sword making.
The late Kamakura period is often referred to as the greatest period of sword making in Japanese history. The Soshu tradition was one of the dominant traditions. Smiths like Kunitsuna and Sukezane combined their knowledge with methods from Yamashiro and Bizen traditions. Finally, a group of famous sword smiths culminated with Masamune (1264-1343 AD) and his school.
The rare swords were made out of five separate pieces and heat-treated at high temperatures. The swords of the Masamune School were harder than any of the swords made before. Masamune trained a group of at least ten followers. Two of his students (Kanemitsu and Nagayoshi) were from the Bizen province. In this way, during the early 14th century, the Masamune school attracted many smiths from other schools. Kanemitsu is believed to be the one who created the Soden School, which combined Bizen and Soshu techniques.
At the same time Chogi was developing his school. The Chogi works show a stronger influence of the Soshu tradition than Kanemitsu swords.
There are several famous schools created by sword masters:
Ornamental plant
An ornamental plant is a plant that is grown for how it looks, and not for its commercial or other value. The term is often shortened to ornamental (usually as a noun) when used in the context of plants.
Ornamental plants are usually grown in the flower garden, or as house plants. They are usually grown for the display of their flowers. Other common ornamental features include leaves, scent, fruit, stem and bark. In all cases, their purpose is the enjoyment of gardeners and visitors. Or to show their beauty. Ornamental plants may also be used for landscaping, and for cut flowers. The cultivation, called floriculture, is a major branch of horticulture.
Ornamental plants come in a range of shapes, sizes and colours suitable to a broad array of climates, landscapes, and gardening needs. They are also often chosen for specialised looks or feels in landscape gardening.
List of garden plants
This is a partial list of garden plants, plants that can be cultivated in the garden, listed alphabetically by genus.

List of plants by common name
The common names of plants often vary from region to region, which is why most plant encyclopedias refer to plants using binomials, or "Latin" names. Common names are also referred to as "country names" or "farmer's names". These names develop over time according to use, appearance, and lore.
Most plants have several country names, and country names often refer to several distinct plants. This list includes garden plants as well as weeds.
This is by no means a complete list. Most of the common names here so far are regional names from North America.

Celts
The Celts were a large group of Caucasian tribes in Europe. They first appeared in the early Iron Age, around 1200 B.C. in Austria. The name 'Celt' comes from the Greeks. The Romans called them "Gauls". They came from the Hallstatt and La Tène cultures. Their culture and genes spread through much of Europe, and by the time the Greeks and later the Romans started emerging, the British Isles and parts of western, southern and eastern Europe were Celtic - the most prominent Celtic tribes were in Gaul. The Celts spoke Celtic languages. Today, the Celtic languages that remain are the Breton, Cornish, Welsh and Gaelic languages.
Celtic society and technology, although not as advanced as the Romans, was far from being primitive for its time. The Celts lived a way of life based on ethical codes and honor codes and had developed a culture of their own, full of unique drawings, sculptures, jewellery, folklore, and building designs and techniques. They were also skilled in blacksmithing, farming and diplomacy.
Celtic warriors would wear war paint and try to scare their enemies by shouting war cries. Tribes had different dress standards for battle; some warriors wore chainmail and/or leather armor, some wore only clothes and some were known to fight fully naked. They also had their own type of sword that was very strong and a shield that was very protective.
