Biologist Rosemary Grant: 'Evolution happens much quicker than Darwin thought'

Biologist Rosemary Grant, along with her husband Peter, conducted groundbreaking research on Galápagos Islands finches, demonstrating that evolution by natural selection can be observed in real time. Their work involved tracking thousands of finches over 40 years, leading to new insights into the speed of evolution. Grant's new memoir, "One Step Sideways, Three Steps Forward," reflects on their journey and the joy of scientific collaboration. The couple's research on the Galápagos finches revealed unexpected speciation processes, challenging Darwin's original theories. Their work emphasizes the importance of preserving diverse species populations to allow for natural genetic variation and adaptation. Grant also shares advice on balancing professional life with parenting, highlighting the value of diverse experiences and quality time with children. The Grants' dedication to studying finches on the Galápagos Islands has provided valuable insights into evolutionary processes and the conservation of species diversity.

The idea that evolution isn't a gradual process of improvement but rather more like a dynamic system, is fairly widely accepted and essentially originates with Stephan Jay Gould.

It's interesting to look all the modern dog breeds and think: "There are very few actual newly mutated genes here, we just encouraged different re-mixes or even un-mixing of an enormous variety that was already latent."

(And then, for a few dog breeds: "I'm so sorry, we have much to answer for.")

Contrary to some of the comments here, I found the article quite interesting. It, along with a paper it links to, describes a very cool study of rapid speciation (over a few generations) observed in the wild. Nice to see the guardian actually link to a paper!

Speaking as a Finch (large F) I am delighted by this study of the finch (small f)

this is just gene characteristics surviving and being passed down.. evolution is a change of species no?..

I remember seeing this posted a few days ago. When I hover over '8 hours ago', it shows '2024-07-22T15:59:19'. That's not 8 hours ago. Why is a post from 4 days ago showing as a recent post? Is it a title change issue?

Regardless. What's the point of the article. We have known for decades that evolution 'can' happen much quicker than darwin thought. From large animals to bacteria. Not only that we know that 'lamarckian' epigentics exists.
