Discussion Overview

The discussion revolves around the geographical distribution of penguins, specifically the yellow-eyed penguin found in New Zealand, and the historical connections between New Zealand and Antarctica during the time of Pangea. Participants explore the implications of genetic divergence and continental drift on species distribution.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions how two genes of the same species can develop in geographically distant locations, specifically New Zealand and Antarctica.
  • Another participant suggests that New Zealand and Antarctica were part of Gondwana, a southern supercontinent, and speculates that penguins may have also lived in Australia before it became too warm for them.
  • A participant expresses self-doubt about their initial question, indicating a concern about its validity.
  • Another participant reassures that the question was not dumb, suggesting a supportive environment for inquiry.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of the geographical distribution of penguins, and the discussion includes both supportive and self-critical perspectives without resolving the initial question.

Contextual Notes

The discussion does not clarify the specific genetic mechanisms involved in the divergence of penguin species or the exact historical geography of the continents involved.

alright, i just read about the 'yellow eyed penguin' that lives in new zealand, and i am wondering how it is possible? how can two genes of same species develop on opposite corners of the world? were new zealand and antartica next to each other in pangea?

New Zealand and Antarctica were both part of Gowandaland, the southern supercontinent that resulted from the breakup of Pangea. I wouldn't be surprised if penguins once also lived in Australia before it became too warm for them as Australia drifted north.
 
now that i am sober that seemed like a dumb question to ask.

No it wasn't.
