What is clear however, is that all organisms are dynamic and will continue to adapt to their unique environments to continue being successful. In short, we are still evolving.
Our bones are becoming lighter
In a 2015 study, scientists hypothesized that Homo sapiens bones started to weaken around 12,000 years ago — around the time that people started farming more. With settled farming, our diets changed, physical activity changed, and, in turn, our skeletons became lighter — and more fragile.
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
Genetic studies have demonstrated that humans are still evolving.
According to the company, humans in the year 3000 could have a hunched back, wide neck, clawed hand from texting and a second set of eyelids.
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.

We will also have larger nostrils, to make breathing easier in new environments that may not be on earth. Denser hair helps to prevent heat loss from their even larger heads. Our ability to control human biology means that the man and woman of the future will have perfectly symmetrical faces.
Human evolution relies on the differences in our genes and in our ability to pass on these genetic differences (ie our breeding capabilities). Over time, the population should change as these differences become more apparent. If the genetic changes are great enough, a new species will arise.
Humans have certainly had a profound effect on their environment, but our current claim to dominance is based on criteria that we have chosen ourselves. Ants outnumber us, trees outlive us, fungi outweigh us. Bacteria win on all of these counts at once.
According to research, we're losing substantial bone strength – with up to 20% less mass than our ancestors had [4]. This trend toward less bone mass is one of the most conclusive signs that we are becoming weaker as a species.
The skull will get bigger but the brain will get smaller
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
Assuming that you and I are not so special as to be born at either the dawn of a very long-lasting human civilization or the twilight years of a short-lived one, we can apply Gott's 95 percent confidence formula to arrive at an estimate of when the human race will go extinct: between 5,100 and 7.8 million years from ...
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 ancestor of Homo sapiens has been named by scientists as part of an effort to clean up our ancestry. Homo bodoensis is named for a skull discovered in Bodo D'Ar, Ethiopia in the 1970s, and is thought to date back to the Chibanian Age 600,000 years ago.
But even if that common ancestor still existed, the fact that evolution is the result of both random mutation and a process of natural selection imposed by environmental conditions, means it's highly unlikely that it would ever retrace its steps in quite the same way.
Around 70,000 years ago, humanity's global population dropped down to only a few thousand individuals, and it had major effects on our species. One theory claims that a massive supervolcano in Indonesia erupted, blackening the sky with ash, plunging earth into an ice age, and killing off all but the hardiest humans.
It has been argued that human evolution has stopped because humans now adapt to their environment via cultural evolution and not biological evolution. However, all organisms adapt to their environment, and humans are no exception.
Basic math tells us that all humans share ancestors, but it's amazing how recently those shared ancestors lived. Thanks to genetic data in the 21st century, scientists are discovering that we really are all descended from one mother.
Humans lost their body hair, they say, to free themselves of external parasites that infest fur -- blood-sucking lice, fleas and ticks and the diseases they spread. Once hairlessness had evolved through natural selection, Dr. Pagel and Dr.
ADAM1 was the first man. There are two stories of his creation. The first tells that God created man in his image, male and female together (Genesis 1: 27), and Adam is not named in this version.
How Human Beings Almost Vanished From Earth In 70,000 B.C. : Krulwich Wonders... By some counts of human history, the number of humans on Earth may have skidded so sharply that we were down to just 1,000 reproductive adults. And a supervolcano might have been to blame.
The planet has experienced five previous mass extinction events, the last one occurring 65.5 million years ago which wiped out the dinosaurs from existence. Experts now believe we're in the midst of a sixth mass extinction.
The earth would become warmer, the average temperature will increase. There will be several new weather patterns and the sea levels would rise. Eventually humans would die out. If the insect population continues to decline, all birds that depend on insect for food will become extinct.
Within the next 200 years, humans will have become so merged with technology that we'll have evolved into "God-like cyborgs", according to Yuval Noah Harari, an historian and author from the Hebrew University of Jerusalem in Israel.
