Between 300 and 400 living species, depending on how you count. Scientists don't always agree on whether two different-looking populations should be considered as different species, different sub-species, or just different populations. There are of course likely thousands of extinct species that arose and went extinct over the last 70 million years or so since the first primates evolved.
There are over 48,000 known species of spiders, and scientists estimate that there could be many more species yet to be discovered. Spiders are found on every continent except Antarctica and play a crucial role in controlling insect populations.

Their population could grow much faster, and they could compete with other species for food.

Add up the individuals who come into an Area and subtract those who leave the area.
Scientists can count a species population using methods such as observational surveys, camera traps, radio tracking, and genetic analysis. These methods help estimate population size and distribution accurately, allowing scientists to monitor changes over time and implement conservation strategies effectively.
The collection of all populations of species in an area is the community.
By analyzing all this data, scientists can learn new ways to help control animal populations, determine what impact development might have on an animal population, and determine if there are enough individuals of a particular species in an area to allow for reproduction.
Scientists would classify these separated members as different species, based on the biological species concept which defines a species as a group of organisms that can interbreed and produce fertile offspring. When geographic isolation prevents interbreeding, the populations may evolve independently and accumulate enough genetic differences to be classified as separate species.
It is difficult to predict which new species is currently in the process of speciation, as speciation is a complex and gradual process that occurs over long periods of time. It often occurs in isolated populations where genetic divergence can lead to reproductive isolation and the formation of new species. Scientists would need to closely study populations showing signs of reproductive isolation to identify a new species in the making.

Scientists use genetics to understand evolution by studying the changes in DNA sequences over time in different species. By comparing genetic similarities and differences between species, researchers can infer evolutionary relationships and timelines. This information helps scientists to reconstruct the history of life on Earth and understand how populations change and evolve.
Birds. there are 500 species of them there.
