Approximately what percent of the speies that have ever existed are on earth today?
.1%
Is it true that 99.5 percent of all species that have ever existed have become exstint?
Yes, it is estimated that about 99.5 percent of all species that have ever existed on Earth are now extinct. This figure reflects the natural processes of evolution and extinction over millions of years, including mass extinction events that have wiped out large numbers of species. Only a small fraction of species that have existed are still present today, highlighting the dynamic nature of life on Earth.
Many species became extinct before mankind started changing the earth?
False. Animals were made the same day as man!!!!! The above is true if you believe exclusively in creationism. Science says that all the species of animals that live on earth today make up less than one tenth of one percent (0.1%) of all the animals that have ever existed. So to answer your question: yes, many species became extinct before mankind altered the earth.
. According to the theory of most of Earth's current species developed from distinctly different species which existed earlier in time.?
The theory you're referring to is evolution, which suggests that species can change over time through a process of natural selection and genetic variation. This means that the diversity of life we see today could have descended from common ancestors that existed in the past.
