1. Comparative genomics assays.
2. Comparative morphology assays.
3. Combining comparative genomics and morphology assays.
4. ...?
By comparing body structures of living organisms...By studying fossils...And comparing the early development of different organisms.
Scientists can learn more about ancestors of different species and organisms by looking at fossil records and observing related species that are alive today.
Comparative anatomy is the investigation and comparison of the structures of different animals. Scientists use comparative anatomy to study the difference between species and how they are alike in other ways. By comparing the similarities and differences between a number of species, scientists can then construct a picture of their evolutionary relationships.
In Peru, one tree was found to harbor forty-three different ant species. Scientists estimate that there are more 22,000 ant species, of which 12,500 have been classified.
there are over two billin different species and the most liked one is a dolphin.(honestly thats just my favorite animal)
they are classified more closely together

I dunnooo :S
There are many ways in which scientists study the evolution of plants. Scientists may choose to study fossils in the area for example.
naming the species, grouping the species.. and more
250,000 Different Species
Scientists study the genetic material of organisms to determine their evolutionary history. By comparing DNA sequences between different species, researchers can identify similarities and differences that help reconstruct the relationships between species and their common ancestors.
Because scientists can cross breed 2 different species to make a new species.
They look different, colored different, eat different things, ect...
Back down the line, the species came from a common ancestor.
One source of information that is used to determine the relationships among different species is DNA. DNA bar coding and macroevolution research provide information at the species level.
There is no definite answer. Some recorded 230 thousand species and counting so by tomorrow there will possibly be a new specie that scientists have discovered. Hope this helps!
