Toll-like receptors were first discovered in fruit flies, and through common descent they were discovered in other species, including humans. Our knowledge of toll-like receptors are vital for understanding immunology, including our knowledge of how vaccines work.
Show me a single thing in the paragraph above that is not true
Too easy ... you can't demonstrate it's "true" (ie, a fact) that it was "
through common descent" that
toll-like receptors were discovered in other species, including humans.
As I've already pointed out, you can't cite even one scientist involved in toll-receptor research who says anything about the role UCD played. In the article you provided, no such scientist even mentions evolution, let alone UCD.
... but you're just being a good and faithful Darwnoid, so lies and bullshit are to be expected.
