Do you have any thoughts on the following, or do we say we don't know?
Hi Eric
Hope your keeping well
There are a couple of things I don’t understand in your post.
I’m
Not sure what you mean when you say natural selection “changes direction “
From what I understand “ natural selection “
Always selects what is beneficial.
I’m not sure what you mean when you say how could “ natural selection detect such a minuscule change “
The changes are played out in nature, and the selection is done by how those changes affect the organisms ability to pass on its genes.
I think it’s also important to note that evolution shapes what is already there,
It was explained to me by a biologist like this
“Imagine a 50 empty gallon barrel, with a tap dripping above it, at a rate of 1 drop per day.
Imagine you look into the barrel after a month, you will see some water
If you came back and looked everyday, for a week, you won’t see much change
If you came back a month later , you might see a little change
If you can back after 2 years , you would see a big change.
It’s still only 1 drip of water
But
A small change, amounts to a big difference over time.
The same is true with evolution
Small changes, amount to a big difference over time.
He went on to explain
“ once you realise the change is happening you can make predictions and test them, if this change is happening then the water level should be at X in 6 months , it should be at Y in 2 years and so on “
The same is true with evolution,
If evolution is true then you can make a prediction, and they have.
They have been able to predict,
A certain type of fossil , being found in a certain age of strata,in a certain area.
They have been able to go and dig and have found the fossil type predicted, predicted on the premise of evolution being true.
It’s this ability to make predictions, that help a hypothesis become a theory
