this was super helpful and easy to understand; thank you!!!

[@nalwangajassy5392]

Thank you so much, you made it much more clear than any one else. Just subscribed wanna see more of your teaching

[@pedroakjr2371]

Clear and objective. I still need to learn how to deal with regressions though.

She expalined it very well.

8:46 The data in the matrix is wrong, which gives the wrong cladogram. Pine trees are more primitive than flowering plants. Pine trees have seeds, but the matrix says they don't (the seeds of a pine tree are in the pine cones). In addition, pine trees don't have flowers, but the matrix says they do. The cladogram therefore has flowers appearing before seeds, which is backwards.

I know - but I was teaching how to create a cladogram from a matrix, not the phylogeny of plants - so it was an exercise in reading the matrix. But thanks for pointing that out - in case someone was watching this for the phylogeny aspect.

@@CalderNation Yeah, I could have been clearer. Based on the matrix, your result was correct. Your method worked, and you didn't make any mistakes.
