how many species have humans made extinct

Long ago, there was a lot more human diversity; Homo sapiens lived alongside an estimated eight now-extinct species of … Each day humans use 40,000 species, most of which go totally unnoticed (Eldredge, 2000). Scientists also debate over how to identify and classify particular species of early humans, and about what factors influenced the evolution and extinction of each species. Although many humans may not realize how important biodiversity is to them, it is clear that without it humans would not be able to exist.

Many early human species -- certainly the majority of them – left no living descendants. The fossil record shows everything goes extinct, eventually. These problems have the potential to cause a major wave of biological extinctions—as many species or populations of a given species, unable to survive in changed environments, die out—and the effects may be harmful to humans and other living things. An extinct flightless bird that inhabited Mauritius, the Dodo was about one metre tall and may have weighed 10–18 kg.

The average lifespan of a species is 1–10 million years, although this varies widely between taxa. 7 Species Hit Hard by Climate Change—Including One That's Already Extinct. Humans have become the biggest selection force in evolution. They were herbivores. This ancient bone belonged to a child of two extinct human species. Loss of Habitat A loss of habitat can happen naturally. Many species, while an individual bird may have a relatively small range, require large habitats for a healthy population to minimize competition for food sources and nesting grounds. that there are around 2 million different species on our planet** - then that means between 200 and 2,000 extinctions occur every year. Coral, polar bears, and frogs are among the species hit hardest. Some disagreement exists about the scientific definition of human.Some scientists date the Homo genus back only 100,000 years while others go back 11 million years and include Neanderthals, chimps and gorillas.Most say early humans first appeared between 2–3 million years ago. The Holocene Extinction, or the Sixth Extinction, has already cost the world thousands of beloved species due to human activity.Although this event has been ongoing for … Many species, while an individual bird may have a relatively small range, require large habitats for a healthy population to minimize competition for food sources and nesting grounds. An endangered species is a type of organism that is threatened by extinction.Species become endangered for two main reasons: loss of habitat and loss of genetic variation. We Homo sapiens didn't used to be alone. If the low estimate of the number of species out there is true - i.e. Humans have vulnerabilities. At the same time, many species may occupy the same range because their food, shelter, and nesting needs do not overlap, and they do not compete individually. When humans cause a species to go extinct, it's like chopping off a branch on the evolutionary tree. Unfortunately for them, many plants and animals living on Earth today are reliant on humans for their survival.
