Life on earth

It was when I first read the book Horseshoe Crabs and Velvet Worms: The Story of the Animals and Plants that Time has Left Behind by Richard Fortey and mentioned in an earlier post entitled Horseshoe Crabs that I first began to read about life and evolution on earth. So when I came across this article entitled “Did Life on Earth Start Due to Meteorites Splashing into Warm Little Ponds?” over at Science Daily, I realized that I want to read more.

Heart of green

Now I’ll be honest with you, I can’t remember if I’ve written about this post before (I’m thinking I might have but I’m not sure) but, either way I writing about it tonight.

Anyway, I’ve been cleaning the house with the kids over at their mom’s house the last two weekends and with all of the research I’ve been doing on retirement, this rather old article that I’ve had for forever, sort of hit close to my (green) heart.

The article is entitled “The Heart of Green” by Annie B. Bond over at Care2. With that I’ll say sweet dreams.

Life on earth, with a little help from space

Ever since I read “Horseshoe Crabs and Velvet Worms: The Story of the Animals and Plants That Time Has Left Behind” by Richard Fortey, the question of how life on earth started has always fascinated me.

This article over at Live Science seems to suggest it’s due in part to meteorites and comets and is entitled “Comet craters: literal melting pots for life on Earth” from Trinity College Dublin. Makes sense to me.

Tree of life

Now I love trees as much as the next person but I have to say I’ve never seen a tree like this one. As the article mentions, it’s a whole lot different than the one that Charles Darwin back in 1837.

The article is entitled “New tree of life doesn’t look as you’d imagine” over at Earthsky. Call me old fashion but, I still like the old one.

Life, as we know it

I remember in biology class back at college learning about classifying plants and animals with terms like kingdoms, classes, orders, families, etc…So when I read this article, I was reminded of that.

The article is entitled “New ‘tree of life’ links 2.3 million species” by Russell McLendon over at Mother Nature Network. Oh, those were the days (back in college, I guess).

DNA or RNA?

I have to admit that reading about DNA and RNA this morning on the way to work, took me back to those biology classes I took in high school. So imagine my amazement when I came upon this article over at NewScientist entitled “Earth’s First Life May Have Sprung Up in Ice” by Linda Geddes.

It talks about how it maybe RNA and not DNA that brought about the first life here on earth. At the same time I was just starting to read chapter 17, What is Life?, in The Mathematics of Life with Ian Stewart also talking about the role of RNA and it’s relationship to DNA.

Wow!

Tree of life

So as we continue on the tree theme here, I thought I would include a couple of articles on what is known as the Tree of Life. The book I’m still trying to finish up, Horseshoe Crabs nd Velvet Worms by Richard Fortey, I came across these two articles on the topic of this process.

The first one is entitled “How Organisms Evolve New Functions: Evolution is as Complicated as 1-2-3” over at Science Daily. Now why’ll Mr. Fortey does lose me mulitple times, it’s been quite fascinating to see how the puzzle pieces of the bigger picture relate.

The other article is “Study of Giant Viruses Shakes up Tree of Life” also at Science Daily. Again, this article loses me sometimes but it’s just amazing how science can track these organisms back in time.

Study on!
