These are physical features shared by organisms with common ancestry they may have the same structure but different functions developmentally mature organisms?
homologous structures
Analogous structures are evidence of?
That different organisms are able to adapt to the same environment.
Plant and animal cells have certain structures in common they also have certain structures that are different Why?
They both evolved from the same multicellular organisms, so they have structures in common. But they did that a long time ago, so they have evolved different structures.
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Homologous structures in organisms suggest that the organisms?
common ancestor

What can homologies reveal about evolution?
Simply common ancestry in the organisms possessing the homologous structures. Compare your arm to your dog or cats forelegs and see common ancestry as they match, bone for bone.
Structures that share a common ancestry or are similar because they are modified versions of structures from a common ancestor are?
Homologous

What is the definition of cladistics?
Cladistics is a method of classifying organisms by common ancestry.
What provide common ancestry among organisms?
Simularities in DNA sequence
What area of taxonomy classifies organisms based on common ancestry?
Phylogenetics classifies organisms based on common ancestry by analyzing their evolutionary relationships using genetic data. This field of study helps to understand the evolutionary history and relatedness among different species.
How is homologous structures an example of evolution?
Though the forelimb of your cat or dog does not look much like your arms these are homologous structures that are almost identical bone for bone. This shows the common ancestry of all tetrapods and the closer common ancestry of you and your mammal pets.
Compare homologous and analogous structures?
Homologous structures are similar in structure but different in function, indicating shared ancestry (such as the bones in the limbs of humans and bats). Analogous structures have similar functions but different origins, suggesting convergent evolution (like the wings of birds and insects).
