What is a term that describes body parts of different organisms that are similar in form?
Homologous structures (Not to be confused with Homologous pairs)
What are Structures in different organisms that share a common ancestry?
Homologous structure
What does it mean if two different animals possess homologous structures?
Homologous structures are similar evolutionary structures that evolved in different organisms that were used for the same purpose long ago but are no longer in use
Why did evolutionary theory prove important in taxonomy?
The homologous structures between different evolutionary structures help taxonomists in classifying organisms.
These are physical features shared by organisms with common ancestry they may have the same structure but different functions developmentally mature organisms?
homologous structures
Are homologous structures similar structures in related organisms?
yes

What are Structures in different organisms that share a common ancestry?
Homologous structure
What should you look for when considering whether structures from two kind of organisms are homologous?
The structures should have similar anatomy in the two organisms.
What does it mean if two different animals possess homologous structures?
Homologous structures are similar evolutionary structures that evolved in different organisms that were used for the same purpose long ago but are no longer in use
What are structures that have different functions in different species but develop from the same embryonic tissue?
Homologous structures
What term describes parts of organisms that have a similar function but not a similar structure?
Homologous Structures
What does the presence of homologous structure in different organisms suggest?
The presence of homologous structures, such as the vertebral column in vertebrates, suggests the presence of a common ancestor. Learn more at 23andme.com.
What evolution has produced many of the analogous structures in organisms today?
They don't. Homologous structures provide evidence for evolution not analogous structures.
What are structures that share a common evolutionary origin called?
Homologous Structures - California LIFE Science Prentice Hall (7th grade)
Why did evolutionary theory prove important in taxonomy?
The homologous structures between different evolutionary structures help taxonomists in classifying organisms.
True or False If two modern organisms are distantly related in an evolutionary sense then one should expect that they should share fewer homologous structures than two more closely related organisms?
True, they should share fewer homologous structures than two more closely related organisms.
