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 !!
Structural similarites
Breeding behavior
Geographical distribution
Chromosome cmparisons
Biochemistry
Scientists will construct what is known as a phylogram to indicate evolutionary relationships between taxa. Probable phylograms are made using molecular and morphological data.
Common traits and genetic.
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.
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.
To show evolutionary relationships based on traits
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.
Biochemical analysis uses similarities in DNA, amino acid sequences, as evidence for evolutionary relationships
Scientists use phylogenic comparative methods to track evolutionary changes over time.
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.
It will stress the evolutionary relationships between different phyla.
They use people.
I dunnooo :S
Common ancestry refers to the shared biological heritage between two or more species, indicating that they all descend from a common ancestor. For example, scientists study common ancestry to understand the evolutionary relationships between different species and trace their evolutionary history.
They see similarities with structures between modern day organisms and older organisms.
