Evolutionary Biology: The evolutionary case for SARS-COV-2 being a man made bio-weapon.

first the conclusion :The most plausible explanation: the Wuhan coronavirus is a bio-weapon made using ZC45/ZXC21 as a template.
"The E protein of β coronaviruses is a structural protein that is tolerant of mutations as evidenced both in SARS and in bat coronaviruses. However, on the amino acid level, E protein of the Wuhan coronavirus identified at the beginning of the outbreak is 100% identical to those of the suspected templates, ZC45 and ZXC21 (Figure 4). What is striking is that, after a short two-months spread of the virus in humans, the E protein is already mutating. Sequence data obtained within the month of April indicate that mutations have occurred to four different locations (Figure 4). Note that the E protein makes very limited interactions with host proteins and thus is not under evolutionary pressure to adapt to a new host. Not only the E protein can tolerate mutations but also its mutational rate is held constant across different coronavirus species. The fact that the E protein of the Wuhan coronaviruses is already mutating in the short period of human-to-human transmission is consistent with its evolutionary feature. In stark contrast, while ZC45/ZXC21 and the Wuhan coronavirus are more distant evolutionarily, the E proteins within them are 100% identical. In no way this could be a result of natural evolution.
Figure 4. Alignment of E proteins of bat and human coronaviruses shatters the notion that the Wuhan coronavirus came from nature. While the early copies of Wuhan coronavirus share 100% identity of the E protein with ZC45, ZXC21, and RaTG13, sequence data of most recent Wuhan coronaviruses indicates that mutation has been observed in four different locations. Accession numbers of viruses (not including the ones listed in Figure 3): Feb_11: MN997409, April_9: MT300186, Apr_13: MT326139, Apr_15_A: MT263389, Apr_15_B: MT293206, Apr_17: MT350246."
Evolutionary biology makes it impossible for the mutation tolerant E protein to be a 100% copy of another distant relative virus (ZC45). The only explanation is that this SARS-CoV-2 virus is man made using the ZC45 as a backbone. Nothing is 100% in evolving nature.
