What do hunter-gatherers eat?
From their earliest days, the hunter-gatherer diet included various grasses, tubers, fruits, seeds and nuts. Lacking the means to kill larger animals, they procured meat from smaller game or through scavenging. As their brains evolved, hominids developed more intricate knowledge of edible plant life and growth cycles.
Are hunter-gatherers happier?

What is a disadvantage of being a hunter-gatherer?
Some disadvantages are not being able to find food when on the hunt. So when hunter-gatherers do not find food they have to stretch their food to survive on what they have provided. The inconstancy of food and supplies, is also a disadvantage. Another disadvantage is being killed by an animal while hunting.
Why did hunter gatherer bands remain small?
The storage of food destroyed the little that remained of the traditional hunter-gatherer band. Groups that had been nomadic, moving every few months in search of food or water holes, became stationary. Now they remained in the same place long enough to grow and harvest small gardens.
What advantages did farming have over the hunter gatherer way of life?
Farming depends on domesticating species. Whereas with hunting and gathering involves the collecting and gathering of wild plants and animals for food. Farming enables a more stable and reliable way of obtaining food. You can farm anywhere as long as you have fertile soil.
How are hunter gatherers better than farmers?
While farmers concentrate on high-carbohydrate crops like rice and potatoes, the mix of wild plants and animals in the diets of surviving hunter-gatherers provides more protein and a better balance of other nutrients.
Did hunter gatherers have more free time?

Is there a hunter Gene?
Hunter syndrome is a very rare, inherited genetic disorder caused by a missing or malfunctioning enzyme. In Hunter syndrome, the body doesn’t have enough of the enzyme iduronate 2-sulfatase.
Is ADHD human evolution?
Summary: The frequency of genetic variants associated with attention-deficit/hyperactivity disorder (ADHD) has decreased progressively in the evolutionary human lineage from the Paleolithic to the present day, according to new research.
How is Hunter syndrome diagnosed?
A definitive diagnosis of Hunter syndrome is made by measuring iduronate-2-sulfatase (I2S) activity. This can be done by taking blood and testing the I2S activity in serum or white blood cells, or by taking a skin biopsy and testing the I2S activity in skin fibroblasts.
What is the chance that a daughter inherits Hunter syndrome?
Hunter syndrome (MPS II) shows X-linked inheritance. On average, a carrier mother will pass on the mutated gene to 50% of her sons and 50% of her daughters.
What gene causes Hunter syndrome?
Hunter syndrome is caused by a variation in the IDS gene, which contains the instructions for the production of a specific enzyme known as I2S. This specialized protein is normally found in the lysosomes of cells, where it helps to break down complex sugars called glycosaminoglycans (GAGs).
What is mucopolysaccharidosis type II?
Mucopolysaccharidosis type II (MPS II) is a rare disease in which the body is missing or does not have enough of an enzyme needed to break down long chains of sugar molecules. These chains of molecules are called glycosaminoglycans (formerly called mucopolysaccharides).
What is Gaucher disease?
Gaucher disease is a rare, inherited metabolic disorder in which deficiency of the enzyme glucocerebrosidase results in the accumulation of harmful quantities of certain fats (lipids), specifically the glycolipid glucocerebroside, throughout the body especially within the bone marrow, spleen and liver.
At what age is Gaucher disease diagnosed?
Although the disease can be diagnosed at any age, half of patients are under the age of 20 at diagnosis. The clinical presentation is heterogeneous with occasional asymptomatic forms.
Which type of Gaucher disease is the most treatable?
With regular therapy, Gaucher disease type 1 is treatable. Treatments either increase enzyme levels or decrease the fatty substance that builds up in the body in Gaucher disease. There is no treatment for the neurological damage from Gaucher disease types 2 and 3.
What is a Type 2 baby?
Type II. Most severe type. A baby has very short arms and legs, a small chest, and soft skull. He or she may be born with fractured bones. He or she may also have a low birth weight and lungs that are not well developed.
