Bacteria As Proof Of Evolution

Wednesday, June 11th, 2008

Some 20 years ago, biologist Richard Lenski, of Michigan State University took a single Escherichia coli bacteria and then kept on feeding it the glucose

one bacteria lead to many and he made 12 different populations that he kept going for 20 years

but then, at about 31 thousand 500 generations of bacteria later, he noticed Escherichia gained the ability to metabolise citrate

the other populations didn’t develop this

now, being careful, Lenski has an archive of every 500 generations stored, so he could replay the process and see if the later generations would develop the same ability (mutation)

the result was, only the original population developed the same mutation when replayed

My Stand On Religion

Thursday, February 28th, 2008

I’m not religious although I was taught by my parents to be

I respect all the religions out there

my parents were not much into religion but they were/are religious

the thing is, there’s so much people around me that pretend to be religious but do all kind of s#it

religion is here something you say you are, do whatever you want (make sins) and then confess before death ;) and everything is fine

well, at least I have the strength to tell the truth

now, my religion stand is best described by what professor Michio Kaku said here

Eating Cloned Animals

Wednesday, January 16th, 2008

Have you ever tasted a cloned animal meat? No?

Well you’re getting lucky today, since the USA FDA ( Food and Drug Administration ) decided that cloned animals are edible.

So, next time you get a piece of pork, cow or a horse you might be eating a cloned animal. Or it’s descendants . The manufacturers are not required to inform you whether you’re eating a cloned animal or not.

The first animal cloned was Dolly the sheep but interestingly FDA didn’t approve cloned sheep because of problems. Dolly died young from a lung infection.

Cloning animals is not without the problems, mostly resulting in defective births or shorter life spans.

The industry found it’s interest in cloning tender cows, rodeo bulls and other special animals. They aim in selling you the offspring from those clones and that only because of economic reasons, it costs 10000 to 20000 per cloned animal compared to 1000 for an ordinary steer.

Sure they’d like you to get only the clones but they can’t afford it ;)

I really don’t know how much will eating cloned animals impact your health. I wouldn’t eat those. Heck I don’t even eat meat, except for the fish.

But it’s strange to have your government make you not distinguish cloned from regular breeding animals. What kind of government is that, are you going to vote for them?

Darwin’s Surprise

Sunday, December 9th, 2007

OK, today I read a preview article called The Role of Retroviruses in Human Evolution on Slashdot and I found it so interesting that I had to read it whole, 8 pages of text here.

What made this an interesting read is that the author claims our DNA contains genetic footprints of various viruses that were bothering us during our evolution.
And this is not only human privilege, other animals have that too.
Darwin used to claim we evolved from monkeys, these people claim we wouldn’t have been the way we are now if it hadn’t been for the viruses changing our DNS (sorry I meant to write DNA, DNS is a domain name server)

The article is written so that anyone can understand it. I highly recommend it :)
