Most scientists believe that birds evolved directly from bipedal, terrestrial dinosaurs.
Birds are very close to reptilesHow will you prove it?
birds are thought to be evolved from reptiles. there is evidence from an anciet organism called archaeopteryx which had bird and reptile features mixed
Most scientist now believe that birds envolved directly from bipedal?
lizards No they believe they evolved from DINOSAURS. But we all know that's not true cause God created birds.
What is an analogous structure?
You can say that they provide the same function for the organism, but their origin i different. For example, bats, birds and dragonflies all have wings, but bone placement isn't present in dragonflies as it is in birds and bats. They all let them fly, but they evolved into that form in different ways. It's two structures (or more) that perform the same function but evolved separately.
