Let’s talk about evo-devo and evolutionary novelties on Friday

It’ll be a casual science convo on Friday at 3pm Central. I’m not going to do a lot of prep work because I don’t have the time, but I can talk about new evolutionary features off the top of my head. How about mammary glands? You like mammary glands?

If you’re one of my patrons (only a dollar a month, cheap), you can also join in the Zoom call. If you hate long-winded livestreams, I’ll also pluck out one of the more interesting excerpts and post that on Saturday.

    BTW, are there any non-mammal species that have invented growing/excreting a nutricious substance for the young/fledgling/ larvae to consume?

  2. Ichthyic says

    some species of cichlids excrete a special protenacious mucous for their young to eat even. some spiders literally give themselves for their kids to eat. many many many examples across all taxa, in fact.

  3. lochaber says

    I believe some of the poisonous dart frogs will lay unfertilized eggs in with their tadpoles as food. Not sure on the details or how wide-spread it is

    Pigeons give so called pigeon milks to their squabs.
