The rather lame German episode title "Ein teuflisches Experiment" (A devilish experiment)is almost certainly not the original title. Here we go:

Challenger, Roxton and Veronica meet Dr. Hargrove ("Dr. Hargrove, I presume. What are you doing in this remote and uncharted Lost World? ;)). They discover that he is undertaking experiments on ape-men. Renata, the young woman that Hargrove introduces as his daughter is also the result of a genetical experiment; Hargrove's daughter died years ago. When Challenger informs Renata about her true identity, she declares her solidarity with the captive apes. Hargrove is killed by his creatures.

As I said, appears to be pretty much the entire episode. Maybe H.G. Wells' heirs should sue the scriptwriters for damages. Yes, sounds definitely like "The island of Dr. Moreau". I know it's difficult to come up with new ideas, however they don't seem to try very hard. Then again, it takes a certain audacity (some would probably say impudence) to steal plot ideas as often and openly as the TLW writing staff does. If they turn the ideas into entertaining episodes, I guess that I wouldn't mind very much. It would, however, be nice to see them becoming a bit more original in the second season. After all, do you guys get paid full when you rip-off dead authors ? ;) But maybe my criticism is premature, let's watch the episode first.
