yes, the DNA evidence suggests that all life on earth, all of the four major branches you speak of, stem from the common ancestor who is today believed by DNA sequencing to be sulfur bacteria.. they are the bottom of the chain (err, the start rather)
technically speaking, there is only ONE kind of life on earth, DNA.
Celine Brochier explains, "The first emerging phyla in the tree of life based on the small subunit of ribosomal DNA (16s rRNA) are hyperthermorphic.. the most parsimonious explanation for this result is that the ability to live in a hot environment is an ancestral trait inherited from the Last Universal Common Ancestor.."
What is the LUCA?

right, but it's the dogmatic religulous that have traditionally led the offensive. like i pointed out, it's the dumb cop at the school board fucking with the biology teacher's pick; it's nt the biology teachers fucking with teaching curriculum at sunday school.

yes, but my momma taught me to treat others as you'd like to be treated.. if some assholes have been fucking it up for thousands of years, why use their tactics? You will only recreate an equally fucked up situation as you started with..
