If you use the micro-macro dichotomy then no Speciation is macro evolution. To be precise, biologists, though many biology texts do not conform, say evolution and speciation.
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.
Evolution
to study dolphins
By selective breeding.
Scientists use mainly fossils.
whattools do scientist use to study meteors
Scientists use an electron accelerator :)
so scientists can detect smaller objects to study
Scientists use a variety of evidence to study prehistoric times, including fossils, geologic strata, archaeological artifacts, DNA analysis, climate data, and isotopic analysis of elements found in ancient specimens. By examining these different types of evidence, scientists can reconstruct past environments, track the evolution of species, and understand human history.
