Did the murderer have anatomical knowledge beyond that of say a butcher?

[Aethelwulf]

I'm curious as to the impact of Prosector's posts.

Reading these boards, prior to his/her posts, my memory tells me the overwhelming consensus was that the murderer didn't have a great deal of knowledge of human anatomy.

What was instructive to someone like me with less than a good knowledge of the murders, was Prosector's posts which made it clear that the two doctors who thought he did possess that knowledge were the two doctors with the most experience in these matters and it follows the two doctors whose opinions carried the most weight. From memory, Prosector detailed certain procedures involved in the murders that required more than the skills/knowledge of say a butcher.

'Just wondering: did these posts change a few minds? what is today's general consensus?

Thanks in advance.

from the chapman case:

Coroner] Was there any anatomical knowledge displayed? - I think there was. There were indications of it. My own impression is that that anatomical knowledge was only less displayed or indicated in consequence of haste. The person evidently was hindered from making a more complete dissection in consequence of the haste.

I'd say the above sounds fairly vague. perhaps the killer did have some rudimentary knowledge from working with animals, and given that annie was most likely killed in daylight, was able to give a false impression. the mortuary sketch of eddowes shows she was cut open with a crude, seemingly hacked zig-zag cut. perhaps this is the result of the same man working in total darkness and by feel, as opposed to by daylight.
