A sputum culture reveals alpha-hemolytic, gram positive, catalase negative cocci that were inhibited by optochin. The bacteria produce acid from lactose. Identify the species of this bacterium.

I was just wondering, what phylums are flowering plants. Wikipedia says it is Magnoliophyta, but my biology teacher says that it is wrong.
All answers must be reasonable and come from a reliable source(wiki doesn't count), and if you are a biologist, goodie.

Are human's today basically genetically the same as human's 1,000 years ago? 5,000 years ago? 10,000 years ago? 20,000 years ago?

People tend to believe the people today are superior in strength and intelligence but is this not only true because we have built opon the achievements of those before us? Is it not true that humans 1,000's of years ago were the same with the same capacity for intelligence. Human's have not evolved in hundreds of thousands of years. Is this not true? The only evolution has been in our technology and knowledge that has accumulated over time by learning from our predecessors, right? No technological knowledge is inate, just learned from those wh invented things and those who made them better. If humans today were put in a world with no technology would it not take them a similar rate to get back to the point that we are at now?

I personally think it's the egg. The animals/mammals might've gotten together and bore a mutated egg which led to the creation of the chicken.

Is there such a thing? I need something like it for my science project (though I want to destroy the very concept of science projects...), but I need it know if there is either an enzyme that speeds up any part of the photosynthesis process (really, any part at all), or a substance that boosts the activity of enzymes in the plant...anyone?

First there was a void, ampty and dark
Then light appeared with the big bang and because of spining matter a night and day effect occured.
Then there was water and sky only as the gaseous ball of our planet cooled.
eventually land appeared.
Plants appeared on the land
Then the sun, moon and stars became visible as the atmosphere cleared up
Then animals appeared in the sea
Animals appeared on the land
Then the conscious, thinking, intelligent human being appeared.
