How do new species form?

Meet the scientists in the Hopkins Lab at Harvard University who are studying how new species form to generate the incredible diversity of life we see on Earth! They are unlocking the scientific secrets of Phlox flowers, examining each step of the Phlox life cycle to discover how species have evolved mechanisms to stay separate and distinct.

Great video ! Love the lab tour !

[@yogesha4727]

I really like the structure of the video.
All aboard the speciation mobile!

[@ScienceIRL]

Vroom vroom!

[@deetlebee]

Loved seeing everyone’s passion and expertise.

[@LuButterworth]

Thanks so much for this, I was really struggling to find accessible info on the speciation of plants!

[@glitch_xix3266]

Here from Lateral. Stayed for the science.

[@ScienceIRL]

yay so glad you're here!

[@tannerbland9827]

Next episode: Reticulate Evolution! 😂

[@ScienceIRL]

Yesss that would be epic!

why hybrid should be sterile? In all movies hybrids are stronger. red queen hypothesis does not work here why?

[@ScienceIRL]

Great question! Hybrids can still be super vigorous and sterile, like the mule. It is a very strong and durable hybrid of a donkey & horse but is sterile and can't reproduce. Hybrid sterility often comes from chromosome incompatibility, but the Hopkins Lab is still working on discovering the exact genetic reasons why some Phlox hybrids are sterile (and some aren't)

Nice, but most of the video is about how a species prevents a new species from forming...
