20+ Distinguish Between Homologous And Analogous Structures Pics. Here’s the difference between homologous and analogous structures: Which is an example of a homologous organ?
Similarities and differences: Understanding Homology and ... from s3.studylib.net The body shape and body color of sharks and dolphins are very similar. Importantly, these changes in dna sequences were only passed to offspring if they were favorable enough to allow the organism to survive long enough to be able to reproduce, a concept known as natural selection. However, phylogenetic trees or evolutionary trees are hypothesized constructions.
Mutation of the dna sequence itself clearly has implications for changing the structures of organisms over time.
Structures derived from a common ancestral structure that may or may not serve the same function in the species are called homologous structures. Both have similar internal bone structure, and as mammals, the evolutionary origin is clearly similar. Surprisingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. A classic example of homologous structures is that of the wing of a bat and the arm of a human.
