No, there is no intelligence in either DNA or evolution.
I can see life evolving as far as the creation of blind, limbless, bone-less worms, but as time went on the DNA in the creatures of this planet
decided that it would grow eyes
No, the predecessor to eyes were not "not eyes", but organs that were worse than eyes in reacting to light.
If reacting to light was essential for survival, then those who reacted to light the best had an greater chance to outlive their peers.
It has been shown quite recently that there are parts of our bodies that react to light. Or rather, that our brains are affected by the body-parts
Also, there seems to be a rule of evolution that doesn't allow for such things as eyes to grow on trees, or for grass to crawl like spiders...
plants are rooted so it's hard not to be rooted. Also, I'm not good at all at plants, but please do think about what else is necessary than an eye
to actually use an eye, and why an eye won't evolve otherwise.
Anyway, if you look at the leaves over a day, you will see how nicely they usually follow the sun.
Trees have been stuck and have remained victims of their environment since the very first tree.
Trees are one of the things on this planet that lives the longest, and that spread out all around the planet without legs. I think they are quite
successful victims - in that case.
It sure seems like they would have evolved a way to become mobile by now, instead of just dropping seeds and hoping that other creatures will move
Wind usually does that to trees, but, they don't need to hope (well, of course they don't, as they don't have any brains), they're doing just
The evolving has occurred in the different climates that have surrounded them. And they now do fine there as well.
Flowers grow pollen in such a way that it requires a totally different species (bees) to transport the pollen from one plant to the next. How could
mindless organisms evolve such cooperation between species?
Before insects, wind took care of it. With insects, suddenly there were accurate agents that were doing a fantastic job. Relying on wind was no longer
a must. Relying on insects can have the consequence that wind is no longer doing a good job. Partly because of how the flowers look, partly because
it's OK with more sparse flowers, as insects know how to find the next flower.
It is said that it takes millions of years for a species to evolve
This is not that accurate. For us to see such an obvious difference, then yes, we need a very long time before we consider two being to be of
, and that evolution takes place when a pattern is repeated over and over, from one generation to the next
No, evolution takes place constantly. Every generation. Every individual.
- like man evolving an opposable thumb to better grasp tools with
That would be a new species, yes.
. Yet, no environment has remained unchanged for more than 100,000 years, not nearly long enough for whole new species to evolve from previous
If it gets colder or warmer, it has no impact on whether or not a thumb will be there.
It will however impact those who are less prepared for it. Those who are not will be the gene-pool that sets the immediate future.
. We have Ice Ages occurring every hundred-thousand years or so. Whole regions of the world have gone from verdant forests to deserts, from oceans to
land, from flat lands to mountains. Forest fires had to have been quite frequent before anyone was around to fight them.
So, if the environments of earth change in less than 100,000 years, forcing life to keep moving into different regions with different climates,
different food sources, different predators, and if evolution takes millions of years, can anyone else see the conflict here?
No, we evolve all the time regardless where we are.
If it takes millions of years for a species to evolve, then that species had to STAY in a set environment for millions of years, while no environment
has remained unchanged for more than 100,000 years.
Why? A human does human things all around the world. And needs human attributes.
