Who Did Humans Evolve From

Charles Darwin thought that humans originated in Africa and that we evolved from ancestors that were different from any species alive today.

How Scientists Discovered The Staggering Complexity Of Human Evolution

Now, a new study by an international group of paleoanthropologists with a wide range of specialties supports Darwin, concluding that the last ancestors we shared with monkeys. Both in modern people and in modern phenomena.

Reviewing the studies on these different approaches, the paper’s authors argue that there are limitations in relying solely on one or the other of these challenging approaches. This is because top-down studies often assume that modern ape species share the habitat and characteristics of earlier groups, while bottom-up studies specify a place evolution more important to individual fossil phenomena than was appropriate.

In an attempt to reconcile these ways to identify our ancient ancestors, scientists looked at what the environment would have been like for the Pan-Homo Last Common Ancestor, or LCA.

The Miocene Era lasted from about 23 to 5.3 million years ago and several fossilized genera from that time have been found. However, they show a combination of features common to both “orthograde” (upright) and “pronograde” (walking on four legs), which has led some scientists to exclude Miocene anemones from the -human lineage, and there is no scientific consensus on the evolutionary role these fossils played.

How Shifting Ancient Climates Shaped Human Migration

Some scientists believe that some of the Miocene apes spread out of Africa and into Eurasia about 16 to 14 million years ago, before humans split from the – monkey. Some of these apes gave rise to the lineage that produced orangutans, and European “dryopith” apes, while others returned to Africa, where they evolved into African apes and hominins. today. Others interpret drypits as an ancestral or evolutionary destination to hominids. .

At the end of the Miocene period in Africa, increased habitat fragmentation resulted from the evolution of African ape walking and hominin bipedalism, or walking on two legs, from orthograde common ancestors that lived in trees. Walking on two legs may have allowed our human ancestors to adapt their diet and locomotion and escape the “special trap” that kept other primates in arboreal environments.

The study concluded that future research efforts should focus on finding Miocene ape fossils in yet undiscovered areas. The scientists decided that data-driven modeling should be prioritized over trying to match evolutionary scenarios to every fossil trace.

Hominin fossils have been found in East and Central Africa and possibly Europe. Fossils of more than 50 generations of ancient monkeys have been found in Africa and Eurasia, however, Dr. Sergio Almesiza, a researcher in the Department of Anthropology at the American Museum of Natural History told Scientific News “…there is no scientific consensus on the evolutionary role of these fossil apes.” “

Climate Change May Have Given Ancient Human Ancestors Bigger Brains, Study Finds

Kelsey Pugh, one of the study’s co-authors, said, “The unique and sometimes unexpected features and combinations of features found in fossil onions, often different from living ones, are needed to eliminate the hominins have inherited from our ape ancestors and are. unique to our generation.”

A new study seems to be sending us back to square one where we came from. Every ancient religion has its own theory of how we came to be. Giorgio A. Tsoukalos, better known as “Hairy Boy,” is a producer of the frequent show “Ancient Aliens”, presenting the theory that humans came from visiting the Earth with ancient aliens. Tsoukalos shares these ideas with Eric von Deniken, Zechariah Sitchin, and Robert K.G. Shared by others including Temple. The Human Edge: Finding Our Inner Fish An important human ancestor was an ancient fish. Although it lived 375 million years ago, this fish called Tiktallik had shoulders, elbows, legs, wrists, neck and many other basic parts that eventually became part of us. This is the first story in our summer series The Human Edge, in which we explore how evolution created the most versatile creature on the planet.

It took years to find in the Canadian Arctic, but in 2004, Neil Shubin found the fossilized remains of what he believes to be one of our most important ancestors.

The Human Edge: Finding Our Inner Fish

Shubin says his discovery, which he named Tictalic, represents an important evolutionary step, as it contains structures that would eventually become part of our human body. Shoulders, elbows, legs, necks, wrists – they’re all on Tiktok.

“We have a big brain, and parts of that big brain aren’t found in Titalic,” Shubin says. “But the template, as far as the DNA that builds it, is already there in these kinds of organisms .”

“It’s like peeling an onion,” he says. “Layer after layer is revealed to you. Just like in the human body, the first layer is our primary history, the second layer is our mammalian history, and you can see the basic molecular and cellular machinery that makes up our bodies and their ‘ keep cells alive. , etc.”

In fact, not only are we related to ancient fish, but many of the components that are essential for making yeast are essential for making us, says Gavin Sherlock, a geneticist at Stanford University.

On The Origins Of

“About a third of all yeast genes that are still in humans have an identical version,” he says.

Sherlock says that humans and yeast still have the same genes, but they are so similar that you can switch one for the other.

“There are hundreds of examples where you can knock out a yeast gene, add the human equivalent, and it normalizes it,” he says.

Think about it, he says: we have a lot in common with yeast. Yeast eats sugar like we do, yeast makes hormones like us, and yeast has sex—not like we do, but sex.

Sex isn’t just fun and games. Genital reproduction is essential to stirring the genetic pot, accelerating the evolution of the most beautiful infinite forms of humans, from fruit flies to blue whales.

Now yeast is a single celled organism. Our body has trillions and trillions of cells – different types of cells, all responding to each other. How did that happen?

Shubin proposes a demonstrative case in the Evolutionary Demonstration. “This tiny diorama here, which you can walk through, is one of the most important to understanding our body,” he said. “What you see in this primitive ocean are organisms such as plastic straws and slimes, but here single-celled organisms like bacteria and other microbes came together to make the first bodies.”

And as time goes by, more forms will appear. Again, Shubin says it’s an easy show to miss. Inside is the old worm: left and right, front and back, top and bottom. These are the same axes of coordination as our bodies.

“In fact, if you look at the evolutionary history of these things, we think that many of the genetic processes that make these organisms and our own organisms came from 500 million years ago,” Shubin says. to say

As Shubin and I walk through the show, we see the results of tinkering with these genetic processes. Evolution brought fish, dinosaurs, mammals. Finally, we come to a familiar 4-foot-tall creature.

This is Lucy, the Australopithecus. She is more like an ape than modern humans, but getting there. Although Lucy has a relationship with humans, she is clearly not human. Australopithecus became extinct.

Evolution: Humans 2.0

Shubin points to a cabinet across the room. Inside is a reconstruction of a prehistoric human burial site. Placed in a grave is the skeleton of a woman, surrounded by her jewels.

“It’s hard to see her as a fossil anymore,” Shubin said. “You look at this as a person who lived, and people love this man enough to do this. And that has changed.”

It’s not bone or muscle or genes that make us human, says Shubin. It was different.

“Physiology and genetics made it possible. This was the template from which it happened,” he says. “But when was that spark, when was that moment? We don’t know.”
