To all you vegetarians, it turns out that you are cannibalizing distant relatives anyway. 

 

I have always thought it rather hypocritical to think that a cow is better than a potato when they are both living things. When you consider that both plants and animals evolved from the same tree (pardon the pun) it seems even more ludicrous to think that being a vegetarian makes you a more conscientious person about the living things we must eat to stay alive.

 

Yes, we understand the cow better since our evolutionary branches are closer on the tree trunk… but that does not mean that a plant is no less worthy to live than is a cow.

 

I never have discriminated against plants. I eat both cows and plants equally… but I do regret having to take any life to sustain my own. As a living being I have no choice but to eat to stay alive though, so this makes a burger, and fries, fair game.

Plants and Animals: Long-Lost Relatives?

Jennifer Viegas, Discovery News

 

Sept. 21, 2007 — Plants and animals may occupy distinct branches on the tree of life, but they could be more alike than we think.

In fact, green plants and animals enjoy a relatively close evolutionary relationship that has been obscured by a narrow focus on DNA sequences to find relatedness, says biologist John Stiller of East Carolina University.

Plants, fungi and animals are all in a group called the eukaryotes — distinguished by their advanced cellular machinery. But some eukaryotes, most notably the fungi, have long been considered more closely related to animals than plants are.

Stiller's theory suggests organisms such as fungi should be given a demotion — placed further from animals on the tree — while green plants should get a leg up.

In a new paper on the subject, accepted for publication in the journal Trends in Plant Science, Stiller outlines the evidence. He told Discovery News that plants and animals have at least five features in common that could not have emerged independently.

"In both green plants and animals, cell cycles are controlled by master switches," he said. "These function, and malfunction, similarly in both groups."

As an example of a shared malfunction, Stiller pointed out that both groups suffer from cancerous growths consisting of rapidly diving cells that grow unchecked.

"The difference is that plants can often simply drop the growth in the way that they drop off their leaves, but humans and animals don't possess that ability," he added.

Another attribute shared by plants and animals, according to Stiller, is the way the genetic material RNA operates in both groups. In both plants and animals, RNA acts as an intermediary between DNA and the protein it codes for. The enzymes that put RNA to work in a cell are similar in plants and animals, but not present in fungi or other organisms, he said.

And like animals, plants have an immune system. For the latter, Stiller argues that certain proteins and genes, which are not present in other organisms, help plants and animals defend themselves against invading viruses and bacteria.

Finally, and possibly most intriguingly, Stiller sees strong parallels between plant neurobiology and animal nervous systems.

"Plants obviously do not have actual nerves and brains, but electrical signals do allow plants to sense and to signal," he explained. "Some of the proteins involved in this process are the same in both groups."

"It is true we don't have a firm idea of the closest relative of green plants," agreed Brent Mishler, a biologist at the University fo California at Berkeley and leader of The Green Tree of Life project, whose primary goal is to trace the lineage of green plants.

"But the green plant-animal hypothesis defended (by Stiller) is quite unusual and will take a compelling analysis to get people to believe it," he added.

Seems to me a few years back (maybe decades?) in a MURDER trial, the only 'witness' to the crime was the plant! And, I do believe that, using some technology that I don't even pretend to understand, they were abole to show that particular plant was reacting negatively to the accused! No other 'test' plant reacted that way, and the person was found guilty based on a plant's 'testimony'!!! Of course, I didn't see the follow up, but I am betting any appeal was won and the killer walked away, but DANG!!! Imagine if we COULD use plants as, well, PLANTS!!!! No more need to place undercover agents in danger (well, the GARDENER might now be in danger, but that's another element we don't need to discuss here)!

In spite of not having a brain... as we know it, plants are aware of their surroundings... at least on some level. After all, it is in the best interest of living things to be somewhat aware of their surroundings.

 

Now, just how aware, and just what plants might actually be aware of... and whether or not there are anything resembling thoughts flowing through their stalks, I cannot say.

 

Still, I am not about to give up having eggs and toast breakfasts even if it turns out that plants are as aware of their environment as a chickens are of theirs. As long as no one proves that wheat is several times more intelligent than chickens are, I have no problem having toast with my eggs for breakfast.

 

However, if one day someone does prove, beyond doubt, that plants are much smarter than anyone knew, then, and only then, would I feel a bit guilty for eating them. But the way I figure it, if plants were that smart they would have figured out how to poison us by now and have become the new masters of the planet.

 

Come to think of it, some plants are poisonous.  Hmmm.  :\ Maybe those are the genius plants of the plant kingdom and one day they will inherit the earth… or take it from us. 

 

Anyway, who knows, but my eggs and toast did taste fine this morning.

I don't think I'd worry about your breakfast Mac...... unless there was a chicken staring at you from across the table.
