Earths first trees

So this was an interesting article to say the least. Apparently earth’s first trees were very different from today’s trees. This according to the article entitled “Primordial Fossils of Earth’s 1st Trees Reveal Their Bizzare Structure” by Laura Geggel over at Live Science. I must admit, very fascinating stuff.

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.

150 Migration paths (simultaneously)

So I written several post’s on the migration paths of various animals but here’s an article and video that talk about and show the migration paths for 150 animals, all at the same time. The article is entitled “Watch 150 Animal Species Roam the Globe in This Amazing Migration Animation” by Melissa Breyer over at Treehugger.

There is also a link in the article to Movebank, an online database of animal tracking data where researchers can share their data. I think the article does a really nice job of showing how other species work in harmony with the planet, rather than against it.

The earth plays hardball

So it seems to some scientist that at one point, the Earth began life with a hard shell (kind of like a turtle shell) that later developed into the plate tectonics we know today. This is however, just the latest study done in a long-standing debate about plate tectonics and earth.

You can read about the study in the article entitled “Earth probably began with a solid shell: New research suggests that plate tectonics began later in Earth’s history” at Science Daily, courtesy of the University of Maryland . Something tells me that this debate will continue for a while.

Close to home

So tonight I’m staying close to home as I post a nice article I found here in my local paper, the Webster-Kirkwood Times. It’s entitled “Earthly Beasts Beware!” by Don Corrigan. I must say I agree.

Mollusks & dinosaurs

Again, two animals I would have never put together. Similar I guess to what they do by studying tree rings to get an idea of what was happening on land, a group of researchers from the University of Florida and the University of Michigan have been doing a little dating, using the shells of the Mollusks in the ocean to also get an idea of what was happening on land.

The article is entitled “The demise of the dinosaurs found recorded in ancient mollusks: Researchers discover evidence of a one-two punch of climate change” by Michael d’Estries over at the Mother Nature Network. It always amazing me how they’re able to work backwards and look at what was happening millions of years ago.

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.
