Today, scientist rely primarily on information about the chemical makeup of cells to determine evolutionary history.
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.
Derived characters are traits that are unique to a particular group of organisms and are used to determine their evolutionary relationships in a cladogram. By identifying and comparing these derived characters, scientists can create a branching diagram that shows the evolutionary history and relatedness of different species.
DNA sequences can be used to create phylogenetic trees by comparing the similarities and differences in the genetic code of different organisms. By analyzing these sequences, scientists can determine the evolutionary relationships between species and construct a visual representation of their evolutionary history.
A derived characteristic is a trait that is unique to a particular group of organisms and is not found in their common ancestor. It plays a crucial role in biological classification by helping scientists determine the evolutionary relationships between different species. By analyzing derived characteristics, scientists can classify organisms into groups based on their shared evolutionary history.
Scientists rely primarily on the fossil record to determine evolutionary history. Another way of determination is examining the genetic record.
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.

I dunnooo :S
they are classified more closely together
Scientists group species on an evolutionary tree based on their shared ancestral relationships. By comparing morphological features, genetic sequences, and other characteristics, they can determine how different species are related to each other and construct a branching diagram that represents the evolutionary history of those species.
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.
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.
Derived characters are traits that are unique to a particular group of organisms and are used to determine their evolutionary relationships in a cladogram. By identifying and comparing these derived characters, scientists can create a branching diagram that shows the evolutionary history and relatedness of different species.
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.
DNA sequences can be used to create phylogenetic trees by comparing the similarities and differences in the genetic code of different organisms. By analyzing these sequences, scientists can determine the evolutionary relationships between species and construct a visual representation of their evolutionary history.
A derived characteristic is a trait that is unique to a particular group of organisms and is not found in their common ancestor. It plays a crucial role in biological classification by helping scientists determine the evolutionary relationships between different species. By analyzing derived characteristics, scientists can classify organisms into groups based on their shared evolutionary history.
DNA sequence analysis provides valuable data for studying evolutionary relationships among different species. By comparing DNA sequences, scientists can determine the degree of relatedness between species, estimate the timing of evolutionary events, and track the accumulation of genetic mutations over time. This information helps to reconstruct evolutionary history and support evolutionary theories.
