When a living organism reproduces, genes are passed from one generation to the next, thus creating hereditary characteristics in the species. Evolution is the process of gradual change in the genetic material of a population of organisms from one generation to the next.
Many believe that evolution is based on natural selection, a process that causes beneficial genetic traits to become more widespread in a breeding population. The process of evolution ensures the survival of all living species. Charles Darwin was an English naturalist who developed the theory of natural selection and provided compelling evidence that all organisms evolved over time from a common ancestor.
Darwin's research had a significant impact on the scientific community and changed the way people viewed many theories of life. Here is a list of the 10 latest signs and evidence that evolution is the actual scientific explanation. You might also be interested to read a top 10 list of arguments that cannot win where evolution or creation is at the top of the list.
1. Stickleback Fish
The stickleback is part of the Gasterosteidae family and can be found in freshwater environments in Europe, Asia, and North America. These creatures have intrigued marine biologists for years, as many populations of fish have evolved through genetic variation and shown great adaptations in bony armor styles. This evolutionary change occurs when the frequency of a rare genetic variant in a single gene of a creature increases.
These fish helped scientists discover that changes in a single gene can make a huge difference in the selector armor and body style of wild fish. He identified a specific genetic mechanism that controls the dramatic change in skeletal patterns. This finding has many implications for the process of genetic evolution of organic species. This will help us discover how new species of animals evolve in nature. The research suggests that evolution can happen rapidly, and that only a few small genetic changes could allow a species to migrate.
to adapt and fill different environments.
2. Darwin's tuberculosis
Darwin's tubercle is a congenital ear disease characterized by thickening of the upper and middle third of the human ear. This feature can be seen in many primates, and this phenomenon was used by Charles Darwin to support his research showing a common ancestor among primates. Today, this feature is present in about 10.4% of the population and in very few newborns. This feature is thought to help animals control and regulate sound. As the intelligence of the human species developed rapidly, the various organs of sight and hearing became unnecessary and gradually moved away from our anatomy.
Humans are also born with a useless and very small third eyelid. It is represented in a small membrane that is visible in the human eye and acts as a protective shield.
Many people believe that the coccyx, or tailbone, proves what the human tail is. Darwin's discoveries about tuberculosis were extremely important in developing the facts surrounding the theory of evolution.
3. Poisonous Australian frogs
The frog problem in Australia is really bad. In 1935, cane toads were introduced to Australia from Hawaii to control the spread of insects that killed the sugar cane crop. This may have been a short-term solution, but the lasting problem is dire. A lethal chemical defense system has been developed to destroy pests that are not good for plants and groundwater.
Experiments on frogs revealed that the creatures that led the land expansion had 6% larger feet than others. A study found that new populations of frogs have longer legs than older established species. This gives the frog the ability to jump higher, move faster and cover more ground on a daily basis. The big mistake of introducing frogs into this environment is a problem that is getting worse every day. Frog species are evolving towards the environment and gaining more protection, which is not good for the Australian economy.
4. Human Influence on Natural Selection
Many studies have been conducted that show that the massive technological development of the human race has a great impact on other organisms. Many species must adapt to human expansion and mass transportation systems. One obvious example is the bee crisis facing many parts of the world. Humans have interfered with the genetics of many bee populations and helped transport different species around the world. This helped spread the tiny Varroa Destructor parasite.
Varroa Destructor feeds on the body fluids of bees and produces a deadly virus that destroys populations. After airplanes, trains, and automobiles were commercially produced, there was a massive expansion of bee populations. One of man's greatest faults in the past was to use various poisons and tricks to solve this evolutionary problem, but this will lead to more abnormalities in the food chain.
Many correlational studies have shown that trophy game such as big fish and caribou breed at a younger age and are smaller in size. Many speculate that this is to combat the hunting and fishing of large human populations that prefer hunting large game. Many species are also affected by the national problem of global warming.
5. Hypolimnas Bolina
The Great Eggfly, also called the Blue Moon Butterfly, is a species of nymphal butterfly found in many parts of the world, including Madagascar, Southeast Asia, Australia, Japan, and New Zealand. It is a black-bodied butterfly with an average wingspan of 7-8½ cm. The butterfly can be found in woodlands, forests, thick and moist bushes and greener parts of uninhabited areas.
In the last decade, scientists realized that a parasite killed all the male members of the genus Hypolimnas bolina on the Samoan islands of Upolu and Savai. The pest infected the females and then killed the males before they hatched. The problem was so serious that in 2001, males comprised only 1% of the population and the species was on the verge of extinction in this part of the world.
Within a year and 10 generations in the family Hypolimnas bolina, the male butterfly evolved and acquired a suppressor gene that prevents the spread of the deadly bacteria. In modern times, the number of men in the colonies on these islands has increased to 40%. Evolution is often more evident in insects because family lineages and life spans are shorter than in primates.
