what is the difference between divergent evolution and convergent evolution in biology
Answers
divergent evolution :---
1) they differ morphologically.
2) they have similar internal structure.
3) they develop in related organisms.
4) they perform different function.
5) they have similar developmental pattern .
convergent evolution:---
1) they show superficial resemblance
2) their internal structure is quite different.
3) they develop in unrelated organisms.
4) they have similar function.
5) they have dissimilar development pattern.

Answer:
CONVERGENT EVOLUTION
Whenone or more different species evolve similarities in their characteristics and functions because of adaptations in an environment.
DIVERGENT EVOLUTION
When an ancestral species diverges into multiple different species, ultimately giving rise to new species.

CONVERGENT EVOLUTION
DIVERGENT EVOLUTION
They evolve from same species and gradually give rise to new species like Darwin finches which have evolved in around 80 new species.
___________________
CONVERGENT EVOLUTION
It is due to change in environmental conditions, or due to the place where they are living.
DIVERGENT EVOLUTION
Due to migration or may be due to environmental changes.
___________________
CONVERGENT EVOLUTION
They live closely in the same way as other species, of which it has adapted the changes.
DIVERGENT EVOLUTION
They live in different ways from their ancestor.
____________________
CONVERGENT EVOLUTION
The outer structure of a species may be different, but internally they resemble their ancestors.
DIVERGENT EVOLUTION
As this type give rise to totally new species, they can be different from outside as well as inside in appearance.

CONVERGENT EVOLUTION
Organisms evolve Analogous structure(means those structure which is similar in function but different in shapes and origin) despite evolving from a different ancestors.
DIVERGENT EVOLUTION
These kind have a Homologous structure (means structure are same, but functions are different), despite appearing similar to ancestors.
