Briefly explain how bat's and bird's wings arr evolution evidence for both homologous and analogous structures
Step by step
Solved in 2 steps
- Given homologous structures like a bird’s wing & whale’s flipper and analogous structures like a bird's wing & insect's wing, prove evolution.referring to Figure 1.20, provide a possible explanationfor how, over a very long time, the green warbler finchcame to have a slender beak.Explain why the shape and size of a bird's beak is the result of natural selection
- Based on the picture, What function do the butterfly and bat wing structures share? How do these structures differ? Give atleast two (2) specific differences. Do these animals share any structural similarities inside their wings that would suggest they are closely related?Do birds and insects share any structural ( elements inside the wings) similarties that would suggest they are closely related taxonomically?You want to construct a cladogram for all species of ducks, which are Birds (Aves). Explain why "presence of feathers" would not be a useful character trait to use to reconstruct their evolutionary relationships.
- If two structures in different species have similar evolutionary origins but different modern-day functions, theyare known as ____________________ structuresGive typing answer with explanation and conclusion to all parts 1. What are the wings of birds and bees are an example of? 1. a homologous character 2. convergent evolution 3. derived characters 4. mosaic evolution 5. ancestral charactersIn a comparison of birds and mammals,the condition of having four limbs is(A) a shared ancestral character.(B) a shared derived character.(C) a character useful for distinguishing birdsfrom mammals.(D) an example of analogy rather than homology.
- Need help Name the three Vertebrate taxa that evolved the ability to fly. Describe which structures were modified for flight in each case, and contrast these structures with those of their closest non-flying relatives. (Please use new species not from previous answers)Search the Internet about the evidence suggesting that birds and dinasours are closely related. If scientist could extract DNA from dinasour fossils, how could they use the sequence to learn more about the origin of birds?Birds are supposed to be the dinosaurs' closest relatives. List and explain five reasons why the Aves have been able to adapt (morphological traits) and survive in the ever-changing world we live into this day.
