This exceptional longevity is explained by a low rate of obesity and a unique diet, characterized by a low consumption of red meat and a high consumption of fish and plant foods such as soybeans and tea.
Racial gaps in life expectancy have long been recognized. The same CDC data show that nationally, Hispanic Americans have the longest life expectancy, followed by white and then Black Americans.
While things like good healthcare and a great diet have helped the Japanese to increase their lifespan, studies suggest they may have a genetic advantage. Two specific genes – DNA 5178 and the ND2-237 Met genotype – play a potential role in extending life by preventing the onset of some diseases.
The average person in Japan is thought to consume approximately 200 fewer calories than an average American person daily, which is thought to be due to higher food prices and traditional dietary habits in Japan, which are often healthier.
Males born in the Lesotho have the lowest life expectancy of the world in 2022. Similarly low is the life expectancy for females born in this country. The average woman lives only 56 years. The lowest life expectancy for women in the world in 2022 was for girls born in Nigeria, with only 54 years.
Life expectancy for Black people was only 71.8 years compared to 77.6 years for White people and 78.8 years for Hispanic people. Life expectancy was even lower for Black males at only 68 years. Data were not available for other racial/ethnic groups.
The world's largest ethnic group is Han Chinese, with Mandarin being the world's most spoken language in terms of native speakers.
Okinawa, Japan
According to Blue Zones, the people living in Okinawa are fortunate enough to have extremely low rates of cancer, heart disease, and dementia compared to Americans. Their longevity can also be attributed to strong social ties, as well as a deep sense of purpose.
Okinawans typically have less cancer, heart disease, and dementia than Americans – and women there live longer than any women on the planet. The Blue Zone suggests that Japan's greatest secret is a strong dedication to friends and family.
Uganda boasts the world's fittest population.
For many Ugandans, staying active is considered a key to healthy living.
Another skeleton from the same cave gave us Neanderthal DNA from 120,000 years ago. But all of this DNA has something in common: Almost all of it comes from Europe and Asia. The oldest DNA from sub-Saharan Africa—the place where the whole human story began—dates back to less than 10,000 years ago.
Abstract. Using gene frequency data for 62 protein loci and 23 blood group loci, we studied the genetic relationship of the three major races of man, Caucasoid, Negroid, and Mongoloid. Genetic distance data indicate that Caucasoid and Mongoloid are somewhat closer to each other than to Negroid.
The fertility rate in the United States in 2020 was 56.0 per 1,000 women ages 15-44. Of all live births in the United States during 2018-2020 (average), 23.7% were Hispanic, 52.1% were white, 15.2% were black, 0.8% were American Indian/Alaska Native and 6.8% were Asian/Pacific Islander.
Findings based on millions of deaths suggest that shorter, smaller bodies have lower death rates and fewer diet-related chronic diseases, especially past middle age. Shorter people also appear to have longer average lifespans.
Mediterranean diet
As the renowned medical journal Lancet points out, eating habits play a key role when it comes to Italians and longevity. A large part of the population can easily bring fresh and healthy food to the table, regardless of social status and income. This is what makes the difference.
The world average age of death is a few years lower at 69.8 years for men and 74.9 years for women. Within the European Union, these are 77.8 and 83.3 years respectively. Birth rate and death rate are given in births/deaths per 1,000 inhabitants within one year. The table shows the official data from the year 2020.
Evidence still suggests that all modern humans are descended from an African population of Homo sapiens that spread out of Africa about 60,000 years ago but also shows that they interbred quite extensively with local archaic populations as they did so (Neanderthal and Denisovan genes are found in all living non-Africa ...
Another popular division recognizes 4 major races
The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid. This is based on a racial classification made by Carleton S. Coon in 1962.
The last “sympatric” humans we know of were Neanderthals, who became extinct only about 30,000 years ago. Since stable separation of parts of the species is the key factor for the formation of new species, we can say that a new split of our species is impossible under current circumstances.
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic Homo sapiens, were dark-skinned.
A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
Publishing its findings in Nature Communications, the study concluded that preserved remains found in Abusir-el Meleq, Middle Egypt, were closest genetic relatives of Neolithic and Bronze Age populations from the Near East, Anatolia and Eastern Mediterranean Europeans.
1. Japan. You might have noticed that Japan frequently tops wellbeing lists online and in the press – and its population is indeed the oldest in the world. Diet plays an important role in this: as an island, there's a natural abundance of fresh fish on the menu, balanced by carbohydrates, vegetables, fruit and meat.
