8 scientific findings prove the theory of evolution is correct

Since science and biology have not yet developed, Darwinian scientist has come up with hypotheses that explain the formation of species on earth. Over time, the following scientific innovations have contributed to prove how great the thinking of this scholar is.

When asked about human origins, up to 42% of Americans still believe that people are created by God, despite numerous scientific evidence of evolutionary theory and natural selection. So, in the period when biology was not developed, Darwin had advanced theories. And below, are scientific findings that support Darwin's theory of evolution.

1. DNA detection

One of the most remarkable things in Charles Darwin's "The Origin of Species" published in 1859, is his theory of evolution in the time when scientists still do not know the genetic mechanism of How does the animal happen? It wasn't until 1950, with Watson and Crick discovering DNA, that we got the correct answer about evolution.

DNA - the answer to genetics.

The development of genome e technology is perhaps the most important contribution to evolutionary biology-related research since Darwin's hypothesis was born. DNA exists in all living things, which means that every species on Earth can evolve from the same ancestor.

The finding also helps explain why natural selection activity, along with mutations in genes, can promote evolution. This process takes place completely automatically without anyone interfering with it.

2. Find fossils

The creatures, born and died, but their life traces still remain. That's what fossils from 3.8 billion years ago teach us. Moreover, fossils with different dates, when arranged in a chronological order, become a chain that can be studied by scientists to study how evolution works so far. . For example, the new fossil found by Pappochelys , a reptile that lived 240 million years ago - became the missing link between two other ancient species, with some characteristics of both. New fossils have been found to play a role in helping biologists fill the gap while understanding evolution.

The fossil of the new Pappochelys has been found to be the missing link between the two other ancient species.

The existence of a multitude of different fossils describes the constant change of nature since the first life existed on earth. From the first protozoan, to the Cambrian period, until the time of dinosaurs and mammals, it became a long story about the process of constantly adapting and developing itself.

In fact, self-adaptive activities are continuous tests to create changes in species in the development of life. Some evolution proved appropriate in the short term, before severe changes in weather, or the emergence of some species of natural enemies - led to species extinction. Some other evolutionary branches, such as birds, are capable of constantly changing and surviving until now. And for species like bacteria, or even crocodiles, almost nothing has changed since ancient times, because they can adapt to almost all living conditions.

3. Find out the same characteristics as your ancestors

Often, researchers evolve or tend to show differences between the current species and their ancestors, but at the same time look for the same characteristics that exist until now. This makes it possible to clearly see the evolutionary process, as well as to show sophistication in species formation.

For example, the structure and morphology of deer, horses, and zebras are relatively similar. Not surprisingly, they have the same ancestral origin. Similarly, seagulls and pelicans have the same origin, so their morphology, habits, even their DNA are relatively similar.

And as Darwin pointed out 150 years ago, these same traits provide important information that contributes to evolution, showing us how organisms change when living conditions are no longer the same. old again.

4. Detecting traces of remnant ancestors

One of the persuasive arguments proving the theory of evolution is the existence of remnants from the ancestors. These properties are disappearing in the process of evolution, because they are no longer relevant to the current living conditions, even harmful.

We have absolutely the basis to "blame" our ancestors for the existence of wisdom teeth that deviate.

Just as the adaptive properties do not appear in "one-way" , the characteristics that are no longer needed take a long time to disappear. For humans, such traits include appendicitis, wisdom teeth and coccyx.

5. Indicate unfinished properties

The current human body, compared to our ancestors, had significant evolution in the past. However, this does not mean that people are perfect creatures, there are still many points that our bodies are still incomplete. For example, the human throat is a place where both food and air to breathe through. This is not to mention how we are unable to synthesize Vitamin C, or how difficult it is for mothers to give birth.

Why do so many people suffer from lumbar spine pain, this position is subject to so much pressure.

Unlike things that are carefully designed, the evolution of animals is not aimed at perfection, but just the ability to adapt itself is enough. Moreover, evolution cannot start from nowhere, but there must always be a starting point for all species, and this can easily lead to features that are no longer needed from the ancestors that have been left behind. wisdom like to deviate, for example).

6. Research on embryonic development

Human embryos and some other animals often share the same shape characteristics at some stage. The general source of ancient genes is one explanation for this.

As explained by Discovery News:

"The ancient genes are evident in the period when the embryo is developing, and there are common characteristics among different species. Human embryos, fish or some other creatures have had tails. , with bearing as well as some other characteristics.
Human embryos have similarities with many other animals because all species still retain ancient genetic code. These gene segments originate from when the first cell appears on Earth. This finding explains why the human embryo has a tail after a few weeks. "

Different species but the embryo remains the same in the first weeks.

Usually the species have close relatives, the more similar the embryo is.

7. Observe evolution in a short period of time

Many people still believe that evolution takes a very, very long time and it is difficult for people to observe. However, in fact, there are times when living conditions change too quickly for some species to change to adapt as soon as possible.

The most typical example for this case is the night species, evolved by the human industrial revolution itself. Previously, this species existed in both black and white, but with industrial plants emitting a lot, making it difficult for the white moth to camouflage. The inevitable consequence is that the black mussel species increased in number, while the white mussel species declined significantly.

Another example is our fight with harmful bacteria. Currently there are many types of bacteria that develop resistance, making many doctors have headaches and worry about a future where there is no way to resist bacteria.

8. Emulate evolution on computers

Another way to witness evolution is to simulate them on computers. Evolutionary researchers have done this for many years, using computers to create simulated environmental conditions that constantly change to monitor natural selection processes. As a result, they can track the evolution over a short period of time, while running the same simulator conditions many times to produce the most accurate results.

Spore - evolutionary simulation game.

Scientists also use the power of evolution to develop drugs and robots. Recently, scientists at Cambridge University have created a robot system capable of creating "children" , and self-assessing their activities to upgrade the design for the next generation robots. .
