Confirmation

Modern birds occupy a wide diversity of
niches and exhibit a variety of behaviors. The
broad structure of our phylogeny suggested diversification
along general ecological divisions,
such as water birds, shorebirds, and land birds.
By "diversification" I take it they are referring to ancestry.
As I have said, the ancestry of birds was into a few major branches with subbranches off those major branches.
The authors of this study confirm this, presenting the major branches as "water birds, shorebirds, and land birds".

 And the authors confirm the subbranching when they say:

Quote:
adaptations to these environments clearly arose multiple times,
They are confirming exactly what I have proposed.

  1. The authors of the phylogenomic study say:
    Modern birds occupy a wide diversity of
    niches and exhibit a variety of behaviors. The
    broad structure of our phylogeny suggested diversification
    along general ecological divisions,
    such as water birds, shorebirds, and land
    birds.

  2. That is what I posted. What point or question are you making?

  3. Ecological diversification is not ancestry.

    You have misunderstood the original article.

  4. The article does not contain the phrase "ecological diversification".
    It says:
    "The broad structure of our phylogeny suggested diversification
    along general ecological divisions,.."

    By "diversification" I take it they are referring to ancestry.
    How do you understand the original article.

  5. Here is how I interpret it:
    The broad structure of our phylogeny suggested diversification [occurred] along general ecological divisions, such as water birds, shorebirds, and land birds.
