mean, think of, say, tropical or temperate marine environments, which have incredibly diverse fish populations. Coral reefs, for example, support over four thousand types of fish, along with sponges, crustaceans and many other organisms. 教授首先说这种一种鱼遍布整片南极海洋的事情很特别,然后提出热...
很多这种细菌被称为极端微生物。 They live in very strange places, in polar ice or in a boiling water of hot springs or in water so salty other organisms couldn’t live there. 它们居住在非常奇怪的地方,比如在极地冰层里,热温泉沸腾的泉水里或者在其它细菌存活不下去的高盐度的水里。 Extremophiles ...
(which makes sense from an evolutionary standpoint since DNA continuously changes as organisms adapt to different environments and a genetic code that spreads more than others would seem to be better adapted) then the honor must go to one of the most unique organisms on the planet: The Pando ...
As a student of zoology, I will always advocate for critical thinking of how basic processes are expressed and utilized across organisms, and recommend excursions and adventures that bring to life the incredible science that makes up life on Earth!" - Trinity Garcia, senior at Texas A&M ...
The question is “what came first, the Universe or Life?” A chicken and egg problem, to be sure, but easily resolved. Since Universe could not have developed *at random*, without some plan and intelligent direction, we must assume that Life came first. We might say that Universe IS Lif...
The first resulted from incredible changes in transport technologies (railroads, steam engines, the first refrigerated train cars, and so forth) in the 19th century, and the second came on the heels of the introduction of huge bulk carriers and the massive harbor-based facilities after World War...
It's beautiful, but it's a world full of struggles between different types of organisms. I can see how Darwin came up with his theory of natural selection, having come to places like this, where you can see these selection mechanisms working all the time.这是个美丽的世界，但也是一个充满...
Living organisms not only adapt to their environment, but also affect it, change the environment within which other organisms may then develop. 活体生物不仅仅要适应环境,还去改变环境,改变环境以后,这个环境可能会变得适宜其他有机体生长。 Likewise, each new mineral also enriches the chemical environment ...
Genomes, for the record, are the unique genetic codes possessed by all organisms. Using Greer's marrow sample, Nolan and his colleagues were able to carry out a detailed whole genome analysis of the Atacama skeleton. When they compared Ata's genetic info to that of various primate species, ...
Beyond these similarities though, what's really fascinating about mineral evolution is the way minerals apparently coevolve with living organisms. Uh, what do I mean by that? Well, it's maybe a billion years after Earth's formation that we first see evidence of life. Of course early life ...
