Today, I am publishing a video.

That is a wonderful video!

We humans are still evolving.

An article in The Conversation caught my eye.

We must never forget that evolution is always happening.

So without any more from me here is that article.

If evolution is real, then why is it not happening now? – Dee, Memphis, Tennessee

Many people believe that we humans have conquered nature through the wonders of civilization and technology. Some also believe that because we are different from other creatures, we have complete control over our destiny and have no need to evolve. Even though lots of people believe this, it’s not true.

Like other living creatures, humans have been shaped by evolution. Over time, we have developed – and continue to develop – the traits that help us survive and flourish in the environments where we live.

I’m an anthropologist. I study how humans adapt to different environments. Adaptation is an important part of evolution. Adaptations are traits that give someone an advantage in their environment. People with those traits are more likely to survive and pass those traits on to their children. Over many generations, those traits become widespread in the population.

The role of culture

We humans have two hands that help us skillfully use tools and other objects. We are able to walk and run on two legs, which frees our hands for these skilled tasks. And we have large brains that let us reason, create ideas and live successfully with other people in social groups.

All of these traits have helped humans develop culture. Culture includes all of our ideas and beliefs and our abilities to plan and think about the present and the future. It also includes our ability to change our environment, for example by making tools and growing food.

Although we humans have changed our environment in many ways during the past few thousand years, we are still changed by evolution. We have not stopped evolving, but we are evolving right now in different ways than our ancient ancestors. Our environments are often changed by our culture.

We usually think of an environment as the weather, plants and animals in a place. But environments include the foods we eat and the infectious diseases we are exposed to.

A very important part of the environment is the climate and what kinds of conditions we can live in. Our culture helps us change our exposure to the climate. For example, we build houses and put furnaces and air conditioners in them. But culture doesn’t fully protect us from extremes of heat, cold and the sun’s rays.

Here are some examples of how humans have evolved over the past 10,000 years and how we are continuing to evolve today.

The power of the sun’s rays

While the sun’s rays are important for life on our planet, ultraviolet rays can damage human skin. Those of us with pale skin are in danger of serious sunburn and equally dangerous kinds of skin cancer. In contrast, those of us with a lot of skin pigment, called melanin, have some protection against damaging ultraviolet rays from sunshine.

People in the tropics with dark skin are more likely to thrive under frequent bright sunlight. Yet, when ancient humans moved to cloudy, cooler places, the dark skin was not needed. Dark skin in cloudy places blocked the production of vitamin D in the skin, which is necessary for normal bone growth in children and adults.

The amount of melanin pigment in our skin is controlled by our genes. So in this way, human evolution is driven by the environment – sunny or cloudy – in different parts of the world.

The food that we eat

Ten thousand years ago, our human ancestors began to tame or domesticate animals such as cattle and goats to eat their meat. Then about 2,000 years later, they learned how to milk cows and goats for this rich food. Unfortunately, like most other mammals at that time, human adults back then could not digest milk without feeling ill. Yet a few people were able to digest milk because they had genes that let them do so.

Milk was such an important source of food in these societies that the people who could digest milk were better able to survive and have many children. So the genes that allowed them to digest milk increased in the population until nearly everyone could drink milk as adults.

This process, which occurred and spread thousands of years ago, is an example of what is called cultural and biological co-evolution. It was the cultural practice of milking animals that led to these genetic or biological changes.

Other people, such as the Inuit in Greenland, have genes that enable them to digest fats without suffering from heart diseases. The Turkana people herd livestock in Kenya in a very dry part of Africa. They have a gene that allows them to go for long periods without drinking much water. This practice would cause kidney damage in other people because the kidney regulates water in your body.

These examples show how the remarkable diversity of foods that people eat around the world can affect evolution.

Diseases that threaten us

Like all living creatures, humans have been exposed to many infectious diseases. During the 14th century a deadly disease called the bubonic plague struck and spread rapidly throughout Europe and Asia. It killed about one-third of the population in Europe. Many of those who survived had a specific gene that gave them resistance against the disease. Those people and their descendants were better able to survive epidemics that followed for several centuries.

Some diseases have struck quite recently. COVID-19, for instance, swept the globe in 2020. Vaccinations saved many lives. Some people have a natural resistance to the virus based on their genes. It may be that evolution increases this resistance in the population and helps humans fight future virus epidemics.

As human beings, we are exposed to a variety of changing environments. And so evolution in many human populations continues across generations, including right now.

This was published for the Curious Kids section of The Conversation.

However, I believe this is relevant for those adults as well who are interested in the subject. I’m in my 80’s and find this deeply interesting.

Death – it comes to all of us!

Irrespective of our believe.

There are only two days in our lives when we live for less than twenty-four hours: the day we are born and the day when we die!

I was born in November, 1944 and that makes me eighty-one. I was born as a result of an affair between my mother and my father. The family genes favour girls over boys, as in seven girls for every boy, and the son is normally the first born. My mother lost her first child, it was a boy. Then my mother had a second baby. Surprise, surprise, it was another son – me!!

I say this as an introduction to a post on The Conversation.

Americans are unprepared for the expensive and complex process of aging – a geriatrician explains how they can start planning

Hollywood legend Gene Hackman and his wife, Betsy Arakawa, were found dead in their home in February 2025. Hackman had been living with Alzheimer’s and depended on Arakawa as his full-time caregiver.

Disturbingly, postmortem data suggests that Arakawa died of complications from pulmonary Hantavirus several days before her husband passed. The discordant times of death point to a grim scenario: Hackman was left alone and helpless, trapped in his home after his wife’s death.

The couple’s story, while shocking, is not unique. It serves as a warning for our rapidly aging society. The U.S. population is aging, but most Americans are not adequately planning to meet the needs of older adulthood.

As a geriatric physician and medical educator, I care for older adults in both inpatient and outpatient settings. My research and clinical work focus on dementia and surrogate decision-making.

In my experience, regardless of race, education or socioeconomic status, there are some universal challenges that all people face with aging and there are steps everyone can take to prepare.

Aging is inevitable but unpredictable

Aging is an unpredictable, highly individualized process that varies depending on a person’s genetics, medical history, cognitive status and socioeconomic factors.

The majority of older Americans report a strong sense of purpose and self-worth. Many maintain a positive view of their overall health well into their 70s and 80s.

But at some point, the body starts to slow down. Older adults experience gradual sensory impairment, loss of muscle mass and changes in their memory. Chronic diseases are more likely with advancing age.

According to the U.S. Census Bureau, 46% of adults over age 75 live with at least one physical disability, and this proportion grows with age. Even those without major health issues may find that routine tasks like yard work, housekeeping and home repairs become insurmountable as they enter their 80s and 90s.

Some may find that subtle changes in memory make it difficult to manage household finances or keep track of their medications. Others may find that vision loss and slowed reaction time make it harder to safely drive. Still others may struggle with basic activities needed to live independently, such as bathing or using a toilet. All of these changes threaten older adults’ ability to remain independent.

The costs of aging

Nearly 70% of older Americans will require long-term care in their lifetime, whether through paid, in-home help or residence in an assisted living facility or nursing home.

But long-term care is expensive. In 2021, the Federal Long Term Care Insurance Program reported that the average hourly rate for in-home care was US$27. An assisted living apartment averaged $4,800 per month, and a nursing home bed cost nearly double that, at a rate of $276 per day.

Many Americans may be shocked to discover that these costs are not covered by Medicare or other traditional medical insurance. Long-term care insurance covers the cost of long-term care, such as in-home care or nursing home placement. However, what is covered varies from plan to plan. Currently, only a small minority of Americans have long-term care insurance due to high premiums and complex activation rules.

I am not aware of any high-quality, peer-reviewed studies that have demonstrated the cost effectiveness of long-term care insurance. Yet, for many Americans, paying for care out of pocket is simply not an option.

Medicaid can provide financial support for long-term care but only for older adults with very low income and minimal assets – criteria most Americans don’t meet until they have nearly exhausted their savings.

Those receiving Medicaid to cover the costs of long-term care have essentially no funds for anything other than medical care, room and board. And proposed federal financial cuts may further erode the limited support services available. In Michigan, for example, Medicaid-covered nursing home residents keep only $60 per month for personal needs. If individuals receive monthly income greater than $60 – for instance, from Social Security or a pension – the extra money would go toward the cost of nursing home care.

Those who don’t qualify for Medicaid or cannot afford private care often rely on family and friends for unpaid assistance, but not everyone has such support systems.

Planning for the care you want

Beyond financial planning, older adults can make an advance directive. This is a set of legal documents that outlines preferences for medical care and asset management if a person becomes incapacitated. However, only about 25% of Americans over 50 have completed such documentation.

Without medical and financial powers of attorney in place, state laws determine who makes critical decisions, which may or may not align with a person’s wishes. For instance, an estranged child may have more legal authority over an incapacitated parent than their long-term but unmarried partner. Seniors without clear advocates risk being placed under court-appointed guardianship – a restrictive and often irreversible process.

In addition to completing advance directives, it is important that older adults talk about their wishes with their loved ones. Conversations about disability, serious illness and loss of independence can be difficult, but these discussions allow your loved ones to advocate for you in the event of a health crisis.

Who’s going to care for you?

Finding a caregiver is an important step in making arrangements for aging. If you are planning to rely on family or friends for some care, it helps to discuss this with them ahead of time and to have contingency plans in place. As the Hackman case demonstrates, if a caregiver is suddenly incapacitated, the older adult may be left in immediate danger.

Caregivers experience higher rates of stress, depression and physical illness compared with their peers. This is often exacerbated by financial strain and a lack of support. It helps if the people you will be relying on have expectations in place about their role.

For instance, some people may prefer placement in a facility rather than relying on a loved one if they can no longer use the bathroom independently. Others may wish to remain in their homes as long as this is a feasible option.

Connecting with available resources

There are local and federal initiatives designed to help aging adults find and get the help they need. The Centers for Medicare & Medicaid Services recently launched the GUIDE Model to improve care and quality of life for both those suffering from dementia and their caregivers.

This program connects caregivers with local resources and provides a 24-hour support line for crises. While GUIDE, which stands for Guiding an Improved Dementia Experience, is currently in the pilot stage, it is slowly expanding, and I am hopeful that it will eventually expand to provide enhanced coverage for those suffering from dementia nationwide.

The Program for All-Inclusive Care of the Elderly helps dual-eligible Medicare and Medicaid recipients remain at home as they age. This program provides comprehensive services including medical care, a day center and home health services.

Area agencies on aging are regionally located and can connect older adults with local resources, based on availability and income, such as meals, transportation and home modifications that help maintain independence.

Unfortunately, all of these programs and others that support older adults are threatened by recent federal budget cuts. The tax breaks and spending cuts bill, which was signed into law in July 2025, will result in progressive reductions to Medicaid funding over the next 10 years. These cuts will decrease the number of individuals eligible for Medicaid and negatively affect how nursing homes are reimbursed.

The government funding bill passed on Nov. 13 extends current Medicare funding through Jan. 30, 2026, at which point Medicare funding may be reduced.

Even as the future of these programs remains uncertain, it’s important for older adults and their caregivers to be intentional in making plans and to familiarize themselves with the resources available to them.

This article is a wakeup call for me, because I have no plan in place.

While I think about death more frequently than I used to, the fact that I don’t have plan is naive: I must get myself to a stage where I have a plan, and soon! I guess I am not the only person in their 80s without a plan!
