Are humans still evolving? Evidence of evolution in humans - Documentary
Hello dear viewers! In this exciting video, we will immerse ourselves in the world of human evolution and explore the continuity of evolution and its impact on humanity throughout the ages. Humans are still evolving, and there is evidence of evolution in the human body
Since ancient times, we have had superficial creation stories and simple explanations to curb the curiosity of the human mind and not delve into the depths of nature, the universe, living organisms, and this amazing world. But are we still evolving as humans? How have these questions failed our minds throughout the ages?
To answer the question: Are humans still evolving? In this video, we will delve into the theory of evolution simply and cite many vivid examples of the evolution of humans in the modern era. We will review the evidence of evolution in our bodies. We will address, as an example, the issue of intolerance of many people in the world to lactose found in milk, which is our inability to digest the lactose found in milk. Milk and dairy products. We will explain how lactose intolerance is due to the genetics of previous generations, as our ancestors did not adapt to drinking milk until the advent of the domestication of dairy animals. Over time, humans evolved and developed the enzyme lactase to adapt to drinking milk.
We will also talk about the impact of the emergence of agriculture on the formation of the human body, how malnutrition resulting from the agricultural revolution affected human health, how the nature of agricultural work affected the human body, and how the average length of the human body decreased during that period. We will focus on the brain and its changes over time. The brain has become smaller over the past 10,000 to 20,000 years because we have relied on external memory to store data. The size of the brain has shrunk, but it has become more specialized and efficient.
As another example of the evolution of the human race, we will talk about the Bajau people and how they could dive for long periods underwater. You will be surprised by studies that have proven that the Bajau people have larger spleens than the average human, thanks to their adaptation to the aquatic environment.
We will also talk about the indigenous people of Australia and how the thyroid gland evolved in their bodies to enable them to withstand the extreme heat in their environment. We will not forget to mention the inhabitants of the Andes and how they evolved to gain immunity to arsenic poison, which is abundant in their drinking water.
Through this in-depth discussion, we will show that humans are still evolving, and that evolution takes a long time over thousands of years to show its influence and new characteristics. Genes and adaptation to the environment play a large role in shaping human evolution.
Let us prepare for an exciting journey into the world of human evolution and how genetic factors and adaptation to the environment have shaped us throughout the ages. Follow us and join us on this exciting journey to explore the depths of our history and our evolutionary future.
