Unexpected family relationships among birds
Among families of fniterstrastar, timalior, glasses and sylvior, the family tree should be rewritten. New research shows unexpected relative relationships between different species within the large bird group.
The garden singer is one of the Swedish birds included in the study. Stock Photography.
It is estimated that species began to divide 18 to 20 million years ago, during the Miocene epoch.
Seven main branches of the bird species were identified and classified during the study. Several birds, previously considered as different species of species belonging to the same species, do not seem to be closely related to the researchers and must therefore be classified as completely different species.
Many species have never been analyzed using genetic methods, and only a few of them are present in Sweden, such as black hair, gardeners and peasants.
Birds particularly like dense undergrowth in the woods, but some live in brush, in dry areas and in wetlands where vegetation is plentiful.
Several follow-up studies on the ecology, development and protection of birds will be carried out on the basis of new discoveries.
