A genome sequence (for a human being) costs about $1000.00 US and takes less than a week.
Mating systems dictate the way in which mutations are partitioned among offspring and therefore can have a profound influence on mutation accumulation from generation to generation. Organisms that reproduce through self-fertilization are thought to be at a lower risk of accumulating mutations as compared to outcrossing or asexual organisms because selfing promotes the expression of recessive alleles, which in turn makes these alleles more visible to natural selection, allowing them to become “purged” from the population
Given the deleterious effects of most mutations, we would predict that increasing the mutation rate should generate progressively larger reductions in fitness, assuming that the mutations accumulate in the genome and that the effects of the mutations are additive or act synergistically . This prediction is generally upheld by most studies that have examined the fitness effects of elevated mutation rates , , –. However, if selfing facilitates efficient purging, then selfing organisms may be capable of absorbing increased mutation rates with few fitness consequences.
As evidenced by the loss of fitness at all EMS concentrations, we see that purging in obligate selfing C. elegans populations is easily overwhelmed by elevated mutation rates (Figure 3). In fact, even marginal increases in mutation rate are capable of overwhelming purging in obligate selfing populations under strong selection against mutation accumulation . Therefore, the efficacy of purging as a mechanism for preventing mutation accumulation may be quite limited, particularly when dealing with mutations of small to moderate effect size at multiple loci.

These so called "past relatives of Homo sapiens, or Humans", are in fact the fossils of the ancestors of the four classes of Big Foot spread through out the world, (which do still roam the Earth today, in the thick forests where man could never survive, and haven't even explored, except from the air) not the ancestors of Humans, or Homo sapiens.
What they don't tell you, is that every living creature, both plant, and animal, are around 98% made up with the same genetic code, because all life, both plant, and animal, were created from the same materials.
Riddle me this Batman, why are there countless amounts of individual species? Why are there still different types of mammals, amphibians, etc.?

Genetic code refers to a translation table from codons to amino acids (see e.g. my thread). What's this bull# about 98% "same"? First plant genome sequenced (A. thaliana) was about 157,000,000 bp in size. The largest plant genome known is about 150,000,000,000 bp in size. Yeast genome is about 6,000,000 bp in size. Human genome is about 3,000,000,000 bp in size. Tell me how these are 98% the same.

The only fact there is, is this moment of presence.
Everything else is fiction (a story about what may or may not have happened).
