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?

Which of the following do cladistic taxonomists not compare when hypothesizing evolutionary relationships among organisms?
They do not compare homologous chromosomes.
What term describes parts of organisms that have a similar function but not a similar structure?
Homologous Structures
What evolution has produced many of the analogous structures in organisms today?
They don't. Homologous structures provide evidence for evolution not analogous structures.
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.
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 did evolutionary theory prove important in taxonomy?
The homologous structures between different evolutionary structures help taxonomists in classifying 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
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Are homologous structures similar structures in related organisms?
yes
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)
Homologous structures in organisms suggest that the organisms?
common ancestor
What are Structures in different organisms that share a common ancestry?
Homologous structure
What is the relationship between homologous structure and analogous structure?
Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.
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.
Structures with no function that are remnants of an organisms evolutionary past are?
VESTIGIAL
Which of the following do cladistic taxonomists not compare when hypothesizing evolutionary relationships among organisms?
They do not compare homologous chromosomes.
What term describes parts of organisms that have a similar function but not a similar structure?
