Organisms that are closely related usually have very similar chromosomes numbers and a large degree of homology (similarity) beween their chromosomes (but the chromosomes are different enough to maintain genetic isolation).
Chromosome comparison is where the DNA of one species is compared to another. For instance, Scientists compare the remains of prehistoric animals to current organisms roaming the Earth in our modern day world.
DNA is often studied to find out about evolutionary relationships. By comparing the similarities and differences in the genetic material (DNA sequences) of different species, scientists can infer their evolutionary relationships and construct evolutionary trees. This field of study is known as molecular phylogenetics.
Protein comparisons, ie. DNA comparisons contribute to evolutionary theory by separating organisms in the plant and animal kingdoms. They go so far as to even separate individuals from one another within the same species. AKA Genetic Code.
DNA comparisons provide the most direct evidence of evolutionary relationships because they reflect the actual genetic changes that have occurred over time in different organisms. By comparing the sequences of DNA, scientists can determine the degree of similarity between species and estimate how closely related they are in terms of their evolutionary history. This molecular evidence is more accurate than comparing physical characteristics because it is less influenced by environmental factors.
Anatomy and physiology are important in determining evolutionary relationships between animal phyla. Similarities and differences in these traits can provide insights into common ancestry and evolutionary history. By studying the anatomical and physiological characteristics of different animal groups, scientists can infer relationships and construct evolutionary trees to understand the evolutionary links between phyla.

Because they love u
study
It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.
Scientists use various methods to compare organisms, including DNA sequencing, morphology, behavior, and ecological data. These comparisons help them understand evolutionary relationships, species diversity, and adaptations to different environments. By studying these differences and similarities, scientists can classify and categorize organisms into different groups.

scientists can infer how closely related the organisms are in an evolutionary sense

The evidence do scientist use to determine evolutionary relationships by scientist have combined the evidence from DNA, protein structure, fossils, early development, and body structure to determine the evolutionary relationship amoung species.
Fish... They open and close there mouth and again, and again etc... Also fish can swim in the sea, there are lots of different types of fish and some can be eaten and yeah laaa !!
