comment Recessiveness of allele for protection of organism
following up on fileunderwater's comment - dominant alleles (if complete) are exposed to selection every time they occur, recessive only when they are homozygous, which means recessive alleles with deleterious effects can persist at low frequencies easily (see Rice 1984 for a discussion related to X chromosome linkage and hemizygosity in males: jstor.org/stable/2408385?seq=1#page_scan_tab_contents) Novel deleterious mutations are not necessarily biased to being recessive as far as I know.

comment Why cannot there be multiple sources for same species origins?
Partly depends on the resolution at which you look (both spatially and temporally) but the further you zoom in the harder it becomes to define where one species becomes two because its a gradual process which takes place over time and space. It's relatively easy to show that humans originate from Africa, harder to show that humans originate from east Africa ~400,000 years ago, and harder to show that humans originated 378,058 years ago in northern Kenya. One part of the problem is pinpointing when homo erectus (?) became homo sapiens which depends on the definition of a species...
