How did the discovery of DNA prove that Darwin’s theory of evolution was correct and how does it change the way we view evolution today and into the future?
Darwin didn’t have any evidence to prove his theory of evolution. His theory explained that all animals come from the same prehistoric animals, which were fish. Over the time, all animals adapted and mutated to create new species that can survive in the new environments that they are introduced to. Humans have evolved from fish, to apes and then to humans. This happened so that we could adapt to our environments. This was part of his theory as well, where he suggested that humans and chimps are relatives, which means that they are both descendants of the same ancestor. That ancestor would be a fish that once existed in the oceans. At the time, he had no hundred percent evidence since science wasn’t as advanced as it is now, but now we have the ability to analyse DNA, we know that Darwin’s theory was correct. Scientists were able to study ape DNA and compare it to human DNA. They found very close similarities in our genes, proving Darwin’s theory that humans and chimps are related. We also found that that humans and apes share 99% of the same genes. Darwin theorized that all animals on the Earth are descendants from fish. This couldn’t have been proven until modern day scientists found Tiktaalik, a prehistoric animal that had a transitional form with a fish body and the same bone structure found in all four-legged animals. This animal proved that his theory was correct because we can see from Tiktaalik how these species moved from the ocean onto land.
Sugar gliders or their scientific name which is Petaurus breviceps. They are an omnivorous species of possum that can glide through the air. They are also marsupials which means that they carry their babies in a pouch. These species belong in the kingdom mammalia just like us humans. These creatures are found in trees and rarely touch the ground. Their membrane or the flaps on each side act like wings which allows them to glide. They are also called sugar gliders because they love the sweet nectar from fruits. So this creature belongs in the mammalia kingdom.
Tropical pitcher plants the scientific name of this plant is called nepenthes. They are a type of plant that belong in the plantae kingdom. They are called pitcher plants because they are a carnivorous plant that have cupped leaves that are filled with liquid that attracts flies and other insects to drink its nectar. The edge of the pitcher plant is slippery which causes whatever is on it to fall in and the plant eats it. The plant belongs in the plantae kingdom because it is an organism that absorbs water and other substances through its roots, and gets energy from photosynthesis.
