Let's break down this meme!

**The Setup: Time Travel and Generations**

The meme uses a common trope in science fiction: traveling back in time. It sets up a contrast between how "boys" (younger, less serious men) and "men" (presumably older, more experienced) would react to encountering their ancestors.

**Top Panel: "Boys with a Time Machine"**

* This panel uses the "Chad vs. Virgin" meme format, though it's subverted here. The "boy" character is surprised by meeting his grandfather and reacts with casual excitement. It’s played for humor—he’s mostly interested in the *novelty* of the situation.

**Bottom Panel: "Men with a Time Machine"**

* This is where the joke takes a serious turn. The "man" character has a grave warning for his past self. It’s a reference to **Dr. Rudolph Schenkel**, a German zoologist.

**The Rudolph Schenkel Reference**

Dr. Schenkel conducted experiments on wolves in the 1960s and 70s. He raised wolf pups in captivity and released them into a wildlife park. He believed this would help him understand wolf behavior. However, these wolves, having not been properly socialized with the natural wolf pack dynamics during critical developmental stages, exhibited bizarre, unnatural behaviors.

* **Lack of Fear:** They showed no fear of humans, approaching people and even becoming friendly.

* **Disrupted Social Structure:** They didn’t know how to hunt properly and couldn't integrate into existing wild wolf packs. They lacked basic survival skills.

* **Abnormal Behavior:** They engaged in play-like behaviors that wolves don't usually display.

The problem was, observers misinterpreted this as evidence that wolves were naturally friendly and could be tamed. This led to a wave of people keeping wolves as pets. This proved to be disastrous, with many attacks and injuries. The "wolf-dog hybrids" created were a burden and often abandoned or euthanized.

**The Meme's Point**

The meme highlights that studying wolves (and perhaps other animals) in captivity can provide misleading information that has severe consequences for both animals and people. The "man" in the meme understands the damage that will be caused by Schenkel's research and desperately wants to prevent it.

It's a darkly humorous comment on the importance of considering the full ecological and behavioral context when studying animals and the danger of drawing simplistic conclusions from artificial environments.
