convergent evolution
If organisms have similar genes, then they are closely related.
embryology
Comparative Embryology- This is the study of similar structures appearing during the embryonic development of related organisms.
The category that most similiar organisms belong to is genus.
all tundras ecosystem have similar features
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
Because they are evolutionarily related - they both had a common ancestor. They have similar body shapes and similar social behaviours.
Co-evolution.
No they are not related. They have similar features but are not related.
yes
In fact the organisms are closely related because the DNA sequences are more similar. DNA sequences are more different as the organism differs.
A group of similar organisms that can produce fertile offspring are species.
If organisms have similar genes, then they are closely related.
analogous because the two features are similar in function yet did not occur due to a shared ancestry. it would be considered homology if the two organisms were somehow related.
