Sea Monster Battle Seen in Prehistoric Bite Marks

This article is about this group of scientis who found a fosil of some kind of respitl-dolphin which fussil show a lot of engury which they infer that the animal must have been a very agressive prepator. "It was a really aggressive encounter" and featured a marine battle tactic not unfamiliar today, said paleontologist Benjamin Kear. Also there have been other founds in Australia of the moster on the sea. They found the reptile-dolphin called Ichthyosaurs, "giant crocodile things" was Kronosaurus and other animals. "Most of what you'd recognize in the oceans today were there, including sharks, shellfish, squid, starfish, and so on," Kear said. "Just take out whales and seals and replace them with ichthyosaurs, giant crocodile things with flippers, weird Loch Ness creatures, and other monsters." This has been a very important discovery since now there is closer look at how the life in the sea during the pre-historic time.

This article interested my because it talks about the living things that where in the sea which is hard to know much about it, since the sea is so big and deep is to hard to look fussils in it which is very bad because it would be very cool to know more about how was life in sea suring the pre-history. I think that to know about the pass and how things were befores is very important.

This is relead to my life because every day things are changing and we are evoluting as people and phisycally. But there are also things out side that are changing and is very interesting to know how was before and how as time pass they change and become what they were before. I think is nice to know about the pass of everything, well for me it is interesting and is relead to my life.

Earth Getting Mysteriously Windier

Over the past 20 years the wind power has increase. It has increase 5% and in the storms about a 10%. The scientist Ian Young have been recording sin 1985 the wind power and he said that "Some regional studies had found similar results, so we suspected there may be an increasing trend,". He record the information using satellite that used a technology kind of like the the natural radar of the bads. Which as the wind blows harder the fainter the echo, giving some measure of the force of the ocean's winds. What causes this is still a mystery, but if this is cause by global warming, this is what Mr. Young says about it "If this is related to global warming—and this is speculation—it indicates that either the intensity of storms is increasing or the frequency of storms is increasing,". Still the consequences of very strong winds can be a desaster for the ecosystem and the cost civilization.

It was interesting for me because it talks about how our plant, our home is changing. Changes are important whether they are bad or good, because depending on the changes we can make decisions and be aware of what are the positive or/and negative things of this change and also what are the thing that we need to change, because as the Earth is changing we need to change with it in order to adapt to it. For this reason is related to my life, because depending on the changes, I may have to change my life in order to survive.

New African Wolf Discovered

ScienceDaily (Jan. 31, 2011) — Scientists studying genetic evidence have discovered a new species of wolf living in Africa.

The discovery, by a team from Oxford University's Wildlife Conservation Research Unit (WildCRU), the University of Oslo, and Addis Ababa University, shows that the mysterious animal know as the "Egyptian jackal" is actually a grey wolf. They explain that grey wolf 3 millions ago were first in Africa before spreading to the north part of the Earth. Professor David Macdonald director of Oxford University's WildCRU, said " A wolf in Africa is not only important conservation news, but raises fascinating biological questions about how the new African wolf evolved and lived alongside not only the real golden jackals but also the vanishingly rare Ethiopian wolf, which is a very different species with which the new discovery should not be confused."

Professor Claudio Sillero, also of the WildCRU, who has worked in Ethiopia for more than two decades, said: 'This discovery contributes to our understanding of the biogeography of Afroalpine fauna, an assemblage of species with African and Eurasian ancestry which evolved. This discovery is a very important because the genetics of this species is new there is no DNA like this gray wolf. Also this may help scientific research about genetics, and evolution. Since this wolf is so rare, scientist encourage the protection and also the change of the name.

I found this article interesting because it talks about genetics which something that in class we are studying in class, not only that also because is about something new that we the humans found and new things are always interesting and is good to know about it.

In our life new things are something that everybody want to know about it. A new type of wolf in Africa is like a super cool found and it shows how cool, interesting and that Earth has lot of surprises and in order to see them we need to take care of it.
