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 don't know for sure I am switching back and forth but don't know what to write. The features seem like homologous features but I am not sure.
I have to answer a similar question for the second chart of features but I am 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 don't know if their structures are different or not.
Can someone please help me I am a little confused I know the definition of both analogous and homologous but can't put them with these features PLEASE HELP QUICK!
