Homologous or Analogous Features?? HELP! PLZ Hi I have a mini lab to do where I had to make two charts and compare features of the brown bat, the orca, the koala, the tiger shark, the black capped chickadee and the human. In my analysis it says from the first chart which has features such as Possessing wings feeding on insects roosting in trees living on land eating mostly plant material living mostly in water possessing structures for swimming feeding on fish having smooth skin lacking body hair lacking earlobes having relatively large size Which species share the greatest number of features. My answer for this question is that the orca and the tiger shark have 5 similar features and the orca and the penguin also have 5 similar features. I am having trouble with the second question it says Would you suspect these features to be homologous or analogous? I dont know for sure I am switching back and forth but dont know what to write. The features seem like homologous features but im not sure. I have to answer a similar question for the second chart of features but im not sure if this one has homologous or analogous features. The features in this chart used to compare the species are: having gills to obtain oxygen having lungs to obtain oxygen having skeletion comprised of cartilage having skeleton comrpised of bone being warm-blooded having feathers arising from epidermis having a four chambered heart producing hard-shelled eggs giving birth without laying eggs producing milk in mammary glands having young that develop internally through placenta I think in this one the features are analogous, they all seem to have similar function but i dont know if their structures are different or not. Can someone please help me im a little confused I know the definition of both analogous and homologous but cant put them with these features PLEASE HELP QUICK!!!!
