Question

Differentiate between homologous and analogous organs or organisms

Answer 1

Homologous organs belong to species of the same evolutionary origin but the organ serves a different function, like the arm of a man and seals flipper. Both mammals with a limb similar in construction, bones, joints tendon s etc. but has a completely different use.

Analogous organs are those from species with different evolutionary origins but serve a similar purpose ie the wing of a bee and the wing of a bird. Totally different species but same organ used to fly.

Answer 2

homologous organs : organs having same structure design but are used for different purposes
analogous organs: organs have different structural designs but are used for the same purpose
