Question
which scenario does not include an appropriate character for a phylogenetic analysis?
1.Some vertebrates have been shown to lactate and produce milk to nourish their offspring. Milk production (lactation) is considered independent and genetically-encoded. Therefore, the production of milk is an appropriate character to include in an analysis of all vertebrates.
2.Tool use is a behavior found in some mammal species and is independent of other characters. This behavior is not genetically-encoded, but it is passed on from parent to offspring. Therefore, tool use is an appropriate character to include in an analysis of all mammals.
3.All bird species are characterized by the presence of feathers. This character state is genetically-encoded and independent of other characters. Therefore, the presence of feathers is an appropriate character to include in an analysis of bird species.
4.Different species of monkeyflowers are known to vary at a gene responsible for salinity tolerance. The variation at this gene is heritable and independent of other characters. Therefore, the salinity-tolerance gene is an appropriate character to use in an analysis of all monkeyflower species.
Explanation / Answer
Answer is 2 as tool use a behavior not a a character found in other vertebrates too.it is not compulsory that all mammals use tool. It can not be considered as a scenario which used as character for phylogenetic analysis.
