/r/ConvergentEvolution
Convergent evolution is the independent evolution of similar features in species of unrelated lineages. For example, birds, insects, bats, and pterosaurs have independently evolved wings.
Post photographs, illustrations, news, articles, videos, and other links related to organisms, living or extinct, that serve as an example of convergent evolution.

Venn Diagram of Gene Sets hint of molecular convergence, imho
Note the Venn diagram here:

A friend pointed out for this to happen outside of convergence:
- The 48 genes shared by humans and chickens were lost in the mice and zebrafish lineages.
- The 43 genes shared by mice and chickens were lost in the zebrafish and human lineages.
- The 57 genes shared by mice and zebrafish were lost in the human and chicken lineages.
- The 73 genes shared by humans and zebrafish were lost in the mouse and chicken lineages.
I think molecular convergence on a protein design is a good explanation.
If the differences are slight enough, then transposition of proteins (horizontal transfer) would neither be a good answer. I might do blast comparisons and molecular clock analyses as well.
Please share you agreements or disagreements that this suggests convergence or not. Thank you in advance.
