Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth. And remember that all the prehistoric plants are also included, because every plant organism is ALSO a species.
Hope this helps, if not, comment below please!!!
Organisms need energy to conduct essential life activities. Basically, energy is essential to every organisms because it is their source of power to get food and to reproduce. Without it, organisms would not function properly and will soon die.
DNA is the molecule that carries genetic information of a given organisms. Genetic variation is the changes that occur in the genome of an organisms to help an organism adapt well to the environment, however, they might also be disadvantageous. The variation in DNA sequences are useful in building a tree of life because DNA sequences are similar in closely related organisms and less similar in less closely related organisms.
