Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition
Answer:
the four zones found in the ocean:
<em>the intertidal zone,</em> which is the area of the seashore that's underwater at high tide and above water level at low tide. this zone also has various kinds of organisms, like seastars, sea urchins and a lot of different species of coral !
<em>the pelagic zone,</em> which could be described as all of the sea other than the sea along the shoreline or the bottom of the ocean. it's funny because the word is actually derived from ancient greek, and the word pelagic literally means
"<em>open sea</em>" !
<em>the abyssal zone,</em> which can also be called the abyssopelagic zone (i don't even know how to say that-) describes the "depths" or the very bottom of the ocean, especially between about 10,000 and 20,000 feet (3,000 and 6,000 m) down !
and <em>the benthic zone, </em>which is made up of the "bottom", like the bottom of a lake or ocean floor, the sediment surface, and some sub surface layers. there's actually organisms living in that zone, too, and they're called benthos ! (i think that's really cute, lil benthos uwu)

To properly build the phylogenetic tree, Julia needs information that can connect any of mentioned mammals (bear and monkey) to reptiles. And that could be only the fact that a duckbilled platypus lays eggs similarly like reptiles. So, the platypus is a mammal and relationship with bear and monkey in that way exist, but laying eggs is not characteristic for other mammals.
