Their environment changed and they could no longer survive.
no one really knows i guess more then 1,000
someone might have mrs. lynch.
It is difficult to estimate the exact number of unknown species, but scientists believe that there are millions of species yet to be discovered, especially in unexplored regions like the deep sea and dense rainforests. Ongoing efforts in biodiversity research continue to uncover new species on a regular basis.

The ancient Greek philosopher Aristotle believed that species are permanent and perfect, meaning they do not change over time and are perfectly adapted to their environments. This concept was known as the theory of essentialism.
The big bang
yes scientists believe that because of the fact they are making a comback in their species.
fossil record
More than half
Scientists believe that changes in the Earth's climate cause extinction of trees;P
Parrot Cichlids are carnivores. I believe they are produced in a Laboratory by some Chinese scientists who artificially fertilise one species of Amazon cichlids eggs with the sperm from a different species. They are not accepted as a species by most Scientists and do not have a proper Taxonomic name.
Many scientists believe that Homo sapiens sapiens interbred with Neanderthals, leading to gene flow between the two species. This interbreeding is thought to have contributed to the genetic diversity of modern humans, with some populations outside of Africa retaining Neanderthal DNA in their genomes.
Scientists believe that Florida was originally connected to another larger landmass due to geological evidence such as similar rock formations, fossil evidence of ancient species found in both Florida and neighboring landmasses, and the theory of plate tectonics suggesting the movement and shifting of land masses over millions of years.
Heaps and heaps just wait until you get there and you will see
Many scientists believe that modern humans first appeared in Africa, specifically in the region of the Great Rift Valley. This is supported by fossil and genetic evidence that suggests an African origin for our species.
Scientists use ancestors and DNA to group species.
it is said to be a lizard type creature ie a reptile. Many people believe it to be a species of hairless dog, whilst scientists believe it to be a coyote with mange.
