How is it possible for a species to maintain its presence in an ecosystem that has changed so dramatically? Here are 5 clear examples of evolution.
Darwin’s theory of evolution established a series of principles that have been held to be true by the scientific community. In an ecosystem we can find species that are able to adapt to changes generated in terms of weather and another range of variables. Evolution has allowed animals and plants continue to live in a particular habitat, What are some of the most unique weapons developed by living creatures? Some of them are just fabulous.
The animal kingdom faces many threats, manifested in the form of changes in terrain or climate, or, simply, by the simple presence of predators seeking to satisfy their hunger. Still, it is worth asking how it is possible that there are a large number of animals that have managed to overcome all these barriers to survive and increase population levels. You know the saying ‘adapt or die’? it is proved in 5 species that have undergone significant changes in their lives.
Let’s, therefore, look at 5 examples that demonstrate how keeping changes in mind can prevent entry of endangered animals, what are Keys to explain the development of these new technologies of defense and of course, the extent to which we are faced with equipment that has been developed in a very short period of time.
These 5 species have evolved to adapt to changes in ecosystems
Below we give 5 examples of evolution showing how there are a large number of animal species that know how to adapt to the new conditions of the ecosystem. Ultimately, this type of species can be used to examine how changes have occurred over the years. Understand the current state of many natural sites, After all, who hasn’t seen how invasive species have completely changed the animal composition of a given area?
The green anole lizards encountered a type of admixture known as the brown anole lizards. Sharing a wide variety of diets, the reduction in available food soon took its toll on the green-choking population. According to information provided by Now, this caused them to adapt to the new situation by taking advantage of the development of new tools. that’s why only after 20 generationsThat is, about 15 years after the introduction of the invasive species, a useful coexistence was achieved.
Of course, it was possible to verify how they had to see their ecosystem displaced. Thanks to the inclusion of offspring with larger and stronger legs, they were able to climb trees, establishing themselves in this new ecosystem and gaining access to new sources of food. this is how it was achieved Maintenance of this species thanks to development A curious evolutionary solution. Otherwise, there would only be brown species today.
A study done with fishes of this class showed How evolution can make a dent in a species in a very short time. To verify the fertility of these animals, a series of samples were introduced to a tobacconist’s shop where the hunters were. The protagonists of the study lived for a certain time in another pond in which there were no dangerous animals. Its purpose was to investigate whether significant changes have been made in the field of reproduction.
It was possible to verify how by moving from one pond to another previous reproductive maturity reached To start with. The fish, in the presence of predators in the water, was able to spawn early. This allowed us to verify how we are faced with a great adaptation to maintain the species in the new framework of coexistence.
chinook salmon have seen how since the 1920s, humans conducted significant fishing expeditions, This has caused a very noticeable loss of specimens, giving rise to a difficult situation for the survivors. The shape of this species has changed over generations, adapting to a new situation. The fall of the pattern has particularly affected people with large sizes, which is why their bodies have shrunk over the decades.
are happening simultaneously Migrants jump because of climate change, Rivers have been estimated to increase by up to 2 weeks due to higher water temperatures, shortening the life cycle. This has contributed to the conservation of species ranging from Alaska to California.
Do you remember when just a few days ago we showed you how there are several species of mosquitoes that are proving to be immune to the use of insecticides? This is not the first behavior in this line. bed bugs have been found a better ability to withstand these chemicals, Compared to units present in the first decades of the 20th century, present ones have thicker shells, more resistant nerve cells and an enzyme that helps break down toxins.
According to information from the BBC, there are bedbugs in New York City which are 250 times more resistant to insecticides Compared to Florida bed bugs. This is a clear example of how those units that survived the use of these products managed to produce offspring with a better ability to cope with this new environment.
In the past, the Finnish owl, an indigenous species present in northern Europe, had, above all, a brown coloration for the purpose of remaining unnoticed in snowy forests. Climate warming and loss of ice cover have created an environment in which Red tones have played a big role, At the same time, this species of owl has introduced these vocalizations to adapt to the new environment.
As winters are warmer in Finland and, therefore, the presence of snow is less frequent, there is an increase in the use of brown textures. Therefore, it is the maintenance of camouflage that aims No one should go unnoticed in the face of the many dangers that may exist forests in which they live. In the same way, it allows to obtain an additional camouflage to hunt its prey, another factor that has influenced to give greater prominence to these colors.
