How organisms evolved in modern times

Do you believe right now, species like aphids, butterflies, bacteria . are still evolving right before our eyes?

See how organisms evolve right before our eyes

Speaking of evolution, people will think of 'long-running' processes that take place in hundreds of thousands or even millions of years. But in fact, the process of urbanization and pollution of human environment is making the process of "evolution" happen faster than ever, especially in the immunity of harmful species .

The creatures below will show you how evolution is happening right before your eyes, right now.

1. Bed bugs know how to metabolize chemicals to deal with toxins

Did you know, ' modern' aphids living in urban areas have completely different characteristics than those found in caves in nature ?

The bugs found in nature are aphids that have been with humans thousands of years ago. As human society grows, people no longer live in caves, migrate and build up cities.

Therefore, bed bugs also change to adapt to life here. They evolved rapidly, in just a few decades, they were separated from the previous 'cave' brother.

Bedbugs now have long, strong legs - making them dance very far with their ability to function at night. Recently, scientists have discovered that these tiny organisms know to increase metabolism and form a special skeleton to deal with toxic substances (such as insecticides).

2. Sea slugs Klepto "stole" gene codes from food to combine their DNA

Experts say this unique snail will steal the genetic code from the food they eat to incorporate into its DNA sequence.

Accordingly, when food in coastal waters becomes scarce, Klepto sea slugs will begin to eat seaweed. This process will cause them to absorb the genetic codes from the seaweed and start producing chloroplasts - a plant biology apparatus that turns sunlight into energy.

It is worth mentioning that the next generation of slugs still inherit this gene from their parents. This is called horizontal gene transfer, which removes the evolutionary limit that took place for thousands of years. However, Klepto nudibranchs still need to eat 'seaweed' to keep the gene from disappearing.

3. Stray dogs possess superior genes

Stray dogs after becoming a stray dog ​​will have characteristics that are superior to wild wolves.

This is understandable and explained by the fact that humans have chosen to make breeding dogs much better than wild wolves . When abandoned, these genes will help them adapt, withstand the surrounding environment so the survival rate is also higher than the native wolf.

4. Black moths "turn" into white butterflies to adapt to the environment

During the industrial revolution in England and the United States, when people began releasing air of all kinds of pollutants , soot hung black on the walls of plants, trees . at this time, moths wore on his white shirt becomes easily detected and eaten by other species.

Gradually, over many generations, the genes of butterflies changed and it was discovered in the city that only black butterflies are left.

Since the 1970s, environmental policies have been enacted and the number of soot in the air has decreased, and black butterflies are now more prone to be detected.

At this time, black butterfly individuals began to find ways to adapt to living conditions. And the number of white moths returned and gradually balanced with the black moths.

5. Bacteria evolved to resist drugs

Did you know, bacterial species are still evolving every day to be resistant to drugs and somewhere among us is facing a ' Apocalyptic scenario'.

The parasite hospitals in the US are finding that some types of bacteria are resistant to the most powerful antibiotics today . This is explained by the abuse of antibiotics worldwide.

When these bacteria adapt to an antibiotic-rich environment, they will evolve and become stronger.

In 2014, in the US alone, 23,000 people died of infections and no antibiotics were effective. Some strains of bacteria that kill more than half of infected patients are becoming increasingly popular in many states in the United States.

6. Fish evolved to create antitoxic proteins

When people started throwing PCBs (a type of industrial toxin) into the Hudson River in 1929, most of the animals were wiped out. However, there is a fish that still survives.

A special species of fish is currently being raised in New York to clean up the seriously contaminated rivers.

In the analysis, the scientists discovered a new gene that helps the fish create an antitrust protein and the gene has never been found in other fish.

This evolutionary process has apparently been going on for only a few decades. Currently, experts are still diligently figuring out which mechanism helps fish to resist this danger.
