Shalom, Kavarim, Banot, and welcome to another very special episode of the world's number one Jewish podcast.

I have to ask for a small favor.

As an independent show, we don't have a massive marketing machine behind us.

Our growth is purely organic, fueled by dedicated viewers and listeners like you.

So if you would be so kind, please take 30 seconds,

head over to Apple Podcasts and Spotify, find this show, and leave me a five-star rating and a short

written review. I love seeing all of your thoughtful and generous feedback. Some of it has even

made it onto the show and may again. And as of this recording,

we are just eight ratings away from hitting 500 on Apple. Crossing that threshold would be a huge

milestone for us. It's a small mitzv on your part, but it really is the fuel that allows us to

keep these amazing conversations going. so thank you in advance.

Unless you don't leave a rating, in which case you're a butthead.

190 years ago, Charles Darwin, the father of evolutionary theory,

arrived at the Galapagos Islands off of Ecuador to study the flora and fauna on behalf of the British Royal Navy.

Among his many discoveries were several dozen birds,

including many varieties of finches, which Darwin assumed were all distinct species, as they appeared to be quite different from one another. Upon further study, however, Darwin realized

they all belonged to a single group within the Finch family. Darwin surmised that a single ancestral finch

species likely arrived on the Galapagos and then diversified across the islands, with natural

selection favoring different traits best suited for different environments. For instance, the ground

finches from one island had thicker beaks for cracking seeds. The cactus finches from one island had thicker beaks for cracking seeds.

The cactus finches on another island had longer beaks for avoiding needles while feeding, etc.

This amazing discovery led to the development of a concept known as adaptive radiation,
