11 Animals That Are EVOLVING To Modern Times! HD

Creatures that are evolving to the modern world! These animals have adapted in recent history to adjust for climate change and other effects of humans 11. Pink Salmon Have Pushed Up Their Migrating Schedules In an instance of one of the most rapid adaptations to climate change, pink salmon are migrating earlier in the year than they did thirty years ago. This is a result of shifting water temperatures. According to researchers, the tendency among these fish to travel from the ocean into rivers to reproduce roughly two weeks earlier than they used to has become genetically ingrained. The change appears to be the result of natural selection, which has conditioned the fish to avoid inhospitably warm waters. 10. The Rise of the Super Bedbug As the number of bedbug infestations has risen over the past few decades, human beings have relied on basic pesticides to keep them at bay. But studies by leading entomologists continue to show that these home-invaders have grown increasingly resistant to both traditional and newly developed poisons. In the instances where bedbugs are vulnerable to the chemicals that used to kill them within minutes, they now take up to seven days to die. Scientists and exterminators now recommend against an overreliance on insecticides, citing a higher need for other remedies such as mattress encasements and traps. 9. African Elephants Are Ditching Their Tusks African elephants were once famous for both their imposing size and the long tusks that differentiated them from most Asian elephants. But over the course of the last century, as poaching related to the ivory trade has diminished their populations across the continent, African elephants have adapted by losing their tusks or passing along the “tuskless” gene to their offspring. While this may arguably make them less of a target for poachers, living without tusks can be a tremendous disadvantage for elephants in the wild. Functioning as extended curved teeth, tusks allow elephants to dig up the ground, strip bark from trees, defend themselves against other animals, and instigate mating rituals. This adaptation is making elephants best-suited to live in human-controlled wildlife preserves rather than the wild they’ve always known. The effect of poaching and big game hunting on this once-iconic mammal serves as a living example of human beings’ collective impact on the planet. 8. Some House Mice Have Beaten the Pesticides Household pesticides used to be the best way to rid a residence of mice or other vermin. But with the significant increase in travel between Europe and North Africa over the past thirty years, Spanish and German house mice have crossed with Algerian mice, a species with whom they had last interacted almost 3,000,000 years ago. The common ingredient in most pesticides is warfarin, a chemical agent originally used by doctors to break down blood clots in their patients. But too high a dosage of warfarin can be fatal, which is why it became a r
