1) What significance does Cosmic/Chemical/Biological origins (And there connection) have, in our endeavors for modern Science?
It's kind of a strange question. It's like asking what significance bread has for food. Bread is food, and the study of origins is science. Learning cosmic, chemical and biological origins is just as much a scientific pursuit as learning how to make a new vaccine.
In any case, biological evolution certainly is useful for understanding all kinds of things in biology. If you want to know the mutation rate in a region of the human genome (something that is useful for all kinds of reasons), for example, the easiest way is to compare the human and chimpanzee genomes; this only makes sense if they share a common ancestor. If you want to find regions of the genome that have been under recent positive selection, you again compare genomes.

2) Could the current origin theories, in this argument, biological, be biased inferences fundamentally based on Darwinist ideas? I.e. Because Darwin observed the similar beaks, inferences regarding similar genomes on a global scale, follow in his evolutionary idea...
Darwinist ideas are used as the basis for inference because they explain and predict data very well. When non-Darwinian ideas do a better job with the data (e.g. with horizontal gene transfer and endosymbiosis), then biologists have no trouble adopting them. If someone wants to replace Darwinian ideas wholesale in biology, all he or she has to do is explain the data better.
