7 Species That Are Evolving Due To Global Climate Change

A list of 7 organisms that have evolved genetically to the extreme climatic shifts.

Change is the most constant thing in nature, and when it comes to climate, the world has gone drastic transformations that have both made and marred species. Be it the ice age, global warming, world pandemic or natural disasters; organisms have altered if not completely perished and found a way to keep up with the ever-changing world. Here are some species that surprise us with their evolution to tackle the crisis of environment change.

  1. Table Corals-
As sensitive as corals reefs are, they are the natural home to algae which have a symbiotic relationship in producing nutrition for the reef. But the higher temperature can disturb the corals, and they can bleach out of food, causing them to die out. Unlike the other endangered species, a table coral Hyacinthus has adapted to the warmer water and withstands being bleached to combat its existence. The heat tolerance might gain their advantage to reproducing and recreating coral islands.
  1. Thyme-
The Mediterranean thyme has been used for its medicinal properties like phenol and deterring herbivores animals. These plants have been a native to the arid region and are sensitive to cold. The warmer conditions and shorter winters have given rise to the growth of these shrubs. They are seen growing in areas where they earlier would not grow.
  1. Pink Salmon-
Fish like salmon are migratory creatures, and with time their evolution has undergone massive changes. The fishes spawn upstream in rivers and go back to the ocean on attaining adulthood. The migration is firmly engraved in their genes. In Alaska, the pink salmon has started migrating two weeks ahead than it was about 50 years back. With the increase in temperature of the water, the fishes have altered their cycle to match the change.
  1. Tawny Owls-
The nocturnal predator of the temperate forest in Europe is usually coloured in brown and faded grey. The pigment totally depends on a pigment called pheomelanin. The colour of the feathers helps them camouflage with the surrounding. With milder winters over the years, there have been more numbers of brown owls with lesser snow to disguise in.
  1. Pitcher Plant Mosquitoes-
The larvae of the pitcher plant hibernate in winters and come as adults in the spring season. They mainly feed on the nectar of namesake plants. With alteration in the climate, these insects have accustomed themselves to delay the process of lying dormant.
  1. Banded Snails-
The colouration of the shells depends both on the genes and surrounding temperature. Lighter tone signifies a colder environment. However, the growth of yellow snails to brown ones in Europe prove the evolution of these creatures to climate change.
  1. Red Squirrels-
Increase in temperature brings early spring and tons of spruce cones. The red squirrels feast on them and produce offspring faster. Their birthing season has undergone drastic shifts and attributed to their genetic change.
