2020 ( evidence record) They find key similarities from pieces from the same species in chronological (usually thousands of years apart) order an then look at what has changed. BTW im not a scientist, just throwing it out there
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
pewp is why
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).
The method used to construct a hypothetical evolutionary tree is phylogenetic analysis, which involves comparing different species' characteristics and DNA sequences to determine their evolutionary relationships. This analysis helps scientists understand how species are related and how they evolved over time. Scientists use various techniques and algorithms to create these phylogenetic trees.
Scientists use cladograms to show the evolutionary relationships between different species based on shared characteristics. By analyzing the arrangement of branches and nodes on a cladogram, researchers can understand the relatedness and common ancestry of organisms. Cladograms help scientists make predictions about evolutionary patterns and can be used to study biodiversity and develop classification systems.
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.
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 structural similarities, such as homologous structures and similar biochemical pathways, to determine evolutionary relationships. These similarities suggest a common ancestry and can help scientists infer how different species are related to each other. By comparing the presence and arrangement of these structures among different species, scientists can construct evolutionary trees to understand the history of life on Earth.
To build a cladogram showing evolutionary relationships among species, scientists can analyze morphological traits (physical characteristics) and genetic data. By comparing similarities and differences in these traits and genetic sequences, scientists can determine how closely related species are and create a visual representation of their evolutionary history.

by comparing them with each other to see wich ones have common ancestors
Modern scientists use genetic sequencing, molecular studies, and evolutionary relationships to classify organisms, techniques that Linnaeus did not have access to. These methods provide a more accurate and detailed understanding of the relationships between different species.
Scientists use genetic evidence to study the DNA sequences of organisms to determine their evolutionary relationships. By comparing genetic information, scientists can classify organisms into groups based on their shared genetic ancestry, which helps in understanding their evolutionary history and developing phylogenetic trees. This method also allows for a more accurate classification of organisms than traditional methods based on physical characteristics.
Scientists use various types of data to determine an organism's phylogeny, including genetic information from DNA sequences, morphological characteristics, and behavior patterns. By analyzing these data, scientists can infer the evolutionary relationships between different species and construct phylogenetic trees that show how these species are related to each other.
