Assertion: Evolutionary trend is continous changes of character in a linage.
Reason: Lineage is an evolutionary sequence arranged in linear order.

Text Solution

Verified by Experts

The correct Answer is:
B
The continous change of the characters within an evoving lineage is called evolutinary trend. A lineage is an evolutionary sequence. Arranged in linear orther from an ancestral group to descendant group. A trent may be progressing (a general increase in size of organs) or retrogressive (a general degeneration and loss of organs.)
