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.

Holding fins?

So to many, hands and fins could in no way have anything in common, right? Well, it turns out that maybe they do. This is according to this article entitled “From Fins Into Hands: Scientists Discover a Deep Evolutionary Link” by

Jellies or sponges?

According to the article entitled “Animal evolution: Sponges really are oldest animal phylum” over at Science Daily by a team from the Ludwig-Maximilians-Universitaet (LMU) in Munich, the winner of who is older is…..the sponge.

In recent years, zoologist have again been debating the topic of which came first but after a re-examination of the evidence, it seems that the answer is the same. Sponges are the oldest animal phylum.

From fins to legs

That title reminds me of an old hardware store we use to have in St. Louis called Central Hardware. Their catch phrase wasfrom scoops to nuts.

Anyway, I love articles on evolution and how we or marine tetrapods got here. The article is entitled “From Fins to Legs and Fins Again” over at EarthSky. Check out how they got here.

No evolution required

I have to say that this is something that I didn’t know happened, let alone for 2 billion years. According to ENN, “Scientist Discover Organism That Hasn’t Evolved in More Than 2 Billion Years“.

The land of evolutionary misfits

It seems like I’ve read a lot of books over the last several years on the topic of evolution and so when I read this article, I knew I had to write a post on it. While for may animals, their place on the tree of life is easy to locate, others are a challenge. This is one of those challenges.

The article is entitled “Evolution Misfit: Misunderstood Worm-Like Fossil Finds it’s Place in the Tree of Life” from the University of Cambridge over at  Science Daily. Don’t forget to heck out the picture that’s with the article. Wow!

Shark week, 325 million years ago

I came across this article a few months ago and thought it would be a great article to post on for shark week. They’re also one of the many amazing creatures discussed in the book The Extreme Life of the Sea by Stephen and Anthony Palumbi.

The article is entitled “Ancient Shark Discovery May Rewrite Our Evolutionary History” by Rich McCormick over at The Verge. It’s really a great read for those of you interested in evolution.
