They are different and have a different purpose, but they are similar and share common traits. Hox Genes -A.B. A synapomorphy implies that a homologous trait, one that is the same in both organisms, was inherited from the same ancestor.A homoplasy, on the other hand, is simply a trait that appeared in different organisms. Wings In Birds And Dragonflies -A.B. For example, the wings of insects, birds and bats are all needed for flying: they are homoplasious structures in the non-evolutionary, as well as the evolutionary, sense. Convergent evolution refers to the process where different organisms evolve to form similar traits, despite not being closely related.This occurs when independent species have had to evolve to survive in similar habitats or have a specific niche to fill. For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. These are analogous structures (Figure 2). Question 3 0.5 pts Bird feathers in warblers and ostriches are an example of homoplasy. Figure: the wings of birds and bats are homoplasies. Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. convergent evolution. A well-known example of homoplasy due to convergent evolution would be the character, "presence of wings". Forelimbs In Horses And Birds -A.B. Homoplasy can arise from both similar selection pressures acting on adapting species, and the effects of genetic drift. Flowers In Angiosperms -A.B. Suppose three species have the following sequence for a portion of the same gene: Based on these data alone, the simplest (most parsimonious) phylogeny would be as follows: Question 4 0.5 pts The fossil record provides more information about ancient cockroaches than about recent walking stick insects. Question: Match The Following Examples To Whether They Are An Example Of Homoplasy Or Homology: -A.B. Question: Question 5 5 Pts Which Of The Following Is An Example Of Homoplasy? Hair In Humans And Bats -A.B. Convergent evolution — the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait — is rife in nature, as illustrated by the examples below. This problem has been solved! parsimony homology. Eyes On Top Of The Head In Crocodiles And Hippopotamus -A.B. This happens often in evolution, as different species evolve to accomplish the same tasks. Anyway, here is the answer. A homoplasy has an older, pre-Darwinian meaning of similarity explained by a shared way of life. We can illustrate an example of how a simple DNA sequence homoplasy arises using a phylogeny. See the answer. One way to avoid such homoplasious characteristics (or, homoplasy) in an analysis is to define the characters more carefully. A homoplasy is the opposite of a homology, or synapomorphy. A. When similar characteristics occur because of environmental constraints and not due to a close evolutionary relationship, it is an analogy or homoplasy. Human Brain And A Chimp Brain B. Butterfly Wings And Bird Wings C. Opposable Thumbs In Chimps And Humans D. Reptile Scales And Bird Feathers ОА OB OC OD. Although the wings of birds, bats, and insects serve the same function, each evolved independently, as can be seen by their anatomy. For example, the wings of the butterfly are completely different from the wings of the hummingbird and bat in terms of their structure and development. Antlers In Antelopes And Staghorn Beetles -A.B. Homoplasy, in biology and phylogenetics, is when a trait has been gained or lost independently in separate lineages over the course of evolution. It seems that you have missed the necessary options for us to answer this question, so I had to look for it. This is different from homology, which is the similarity of traits can be parsimoniously explained by common ancestry.
