Here are the four postulates of natural selection, according to Charles Darwin:
1. variability - refers to different mutations that create different species
2. heritability - refers to the genes that are passed from one organism onto its descendants
3. overproduction of offspring - refers to the fact that more "children" is born than dies
4. natural selection - refers to those organisms that survive because they adapt to their surroundings better than those who will die
Answer:
The earliest known life-forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 billion years ago, relatively soon after the oceans formed 4.41 billion years ago, and not long after the formation of the Earth 4.54 billion years ago.
Explanation:
yes they are you are right
So that scientists all over the world know exactly what organism is being discussed or investigated Classification of organisms is important because it greatly expands researchers' ability to make educated guesses about particular species. For instance, in many cases, a particular organism may be both difficult to study and also threatened or endangered, or even human and ethically incapable of being experimented upon. However, a related organism may be quite similar to the species of interest, yet not threatened or endangered and without ethical concerns. I see this implementation of classification in the field of herpetology all the time, but it is true across the board in biology
