Evolutionary grades, being united by gross morphological traits, are often eminently recognizable in the field.

However, other data concerning immunology and other morphological traits fail to support this close relationship.

Of course, matching this molecular data to morphological and behavioural traits would make for some interesting reading, in my humble opinion.

T.tana has been described as mainly terrestrial based on field observation and their morphological traits.

A tutorial examines morphological traits, and color photographs are included to simplify the identification process.

They hold at least eleven morphological traits in common, which are not found on other birds.

Both have unusual life histories and morphological traits associated with this habit.

These genes are needed for the morphological or functional traits of the cell.

The family is permeated with unusual morphological traits, many of which are limited to males.

However, the presumed large and small forms cannot be distinguished by morphological or meristic traits.
