6. How can a hypothesized phylogeny that is implied by the Linnaean classification of a group o 7. What is the function of the outgroup in a cladistic analysis? 8. Butterfies have wings and bats have wings. Is this similarity a homology or analogy? Expl 9. Describe two characteristics shared by all living organisms, and which are probably homologous among all organisms. g. What factors cause some organisms to look superficially similar despite the lack of a close ancestral relationship among them ancestral relationship among them? As part of your answer, give an example of two organisms with analogous traits.

Explanation / Answer

Question:- 7

Ans:- In Cladistics or Phylogenetics , an outgroup is a group of organisms that serves as a reference group when determining the evolutionary relationships of the Ingroup, the set of organisms under study and it distinct from sociological outgroups. The outgroup is use as a point of comparison for the Ingroup and specifically allows the phylogeny to be rooted.

Question 8:-

Ans:- Analogy , means bats and butterflies wings are not simmilar anatomically but they perform same funtion as Flying hence this is called analogous structures or analogy.

Question 9:-

Ans:- All organisms are made up of Cells which reproduce and having metabolism and they react from action.

?Question 10:-

Ans:- temperature , water, Food are the important factors and examples of analogous structures are bats and birds.eye of octopus and of mammals or ther flippers of penguins and dolphins.
