North of London | Perhaps you just have not researched enough so try looking up how the whales evolved from a mammal on land to the mammal we now have living in the ocean with out legs.
Or look up Tiktaalik
And another peculiarity is the recurrent laryngeal nerve in the giraffe
All examples of evolution that took millions of years.
How about the Peppered Moth that changed colour when environment changed.
That happened recently in relatively short time so humans were able to see it and record it.
Study the history of corn and how humans forced a small plant, teosinte, with hard seeds to change to what we now grow and use by millions of tonnes every year.
A 'force' that selects for mutations is all it takes.
With higher yielding crops or better producing livestock the 'force' is humans but through the eons the environment has been the force whether climate or other species hunting a species | |
