-
perpetual change (always changing)
-
Common descent (living things have unified history, life comes from life)
-

Questão 34
Questão
Darwin's 4 postulates are:

inheritance - the differences are passed down from parent to offspring
-
some individuals are more successful at surviving and reproducing than others
-
the successful individuals are not merely luck, but succeed because of the variant traits they have inherited and will pass onto their offspring

gradualism

perpetual change

Responda
- True
- False
Questão 37
Questão
[blank_start]Adaptation[blank_end] is an inherited characteristic of an organism that enhances their survival and reproduction in specific environments. A trait that increases an organism's fitness relative to individuals lacking it is called [blank_start]relative fitness[blank_end]; the contribution an individual makes to the gene pool of the next generation via [blank_start]reproduction[blank_end].

-
Adaptation
-
relative fitness
-
reproduction

Responda
-
individuals
