How do scientists use scientists use structural similarities to determine the evolutionary relationship?
They see similarities with structures between modern day organisms and older organisms.
What evidence do scientists use to make phylogenetic trees?
Phylogenetic trees represent hypotheses about the evolutionary relationships among a group of organisms. A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups.
What are structures that share a common evolutionary origin called?
Homologous Structures - California LIFE Science Prentice Hall (7th grade)
The science of structure and the relationships among structures?
anatomy
Derived characters are used to construct a cladogram?
Cladograms determine evolutionary relationships between organisms by examining shared derived characters. A cladogram is simply a diagram that illustrates the relationships among organisms.
Why do scientists combine evidence from fossil fuels body structures and early development and DNA and protein?
Scientists want to determine the evolutionary relationships among different species.
Explain why the homologous structures in Part 1 are evidence of evolutionary relationships?
Homologous structures are the remnants of structures long ago that have evolved into other things now. This is why they are evidence of evolutionary relationships.
Scientists group species on an evolutionary tree based on what?
gene similarities, physical structures, and fossil record.
How do scientists use comparative anatomy to study evolution?
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.
How do scientists use scientists use structural similarities to determine the evolutionary relationship?
They see similarities with structures between modern day organisms and older organisms.

Why did evolutionary theory prove important in taxonomy?
The homologous structures between different evolutionary structures help taxonomists in classifying organisms.
What are four different ways scientists get info about the evolutionary history of an species?
By comparing body structures of living organisms...By studying fossils...And comparing the early development of different organisms.
What describes the position and relationships of structures?
what position is used to describe the position and relationships of structures
Structures with no function that are remnants of an organisms evolutionary past are?
VESTIGIAL
Why do vestigial structures provide a clue to the evolutionary history of a species?
they are remnants of structures found in the ancestral species
What is the evolutionary process that produces analogous structures called?
The Kravic's cycle
