The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.
Answer:
- Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions
- Fossils of marsupials were originally the same across South America and Australia
- Cratons match across the edges of continents
Explanation:
South America, Africa, Antarctica, and Australia were all once part of one super-continent. This super-continent has been named Gondwanaland. As the geological processes got more intensive though and Gondwanaland separated into smaller land masses, continents, which we now know as the continents on the Southern Hemisphere. There are numerous clues that confirm that these continents were once connected. Some of the clues are the matching cratons on the edges of the continents, the glacial deposits and scratches in the bedrock are also matching, lot of fossilized flora and fauna from the same species have been found in several of these continents, the marsupials in South America and Australia etc.
Answer:
I guess it is a Secondary Succession.
Explanation:
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation.
The answer is genetic drift (bottleneck effect)
<span>There are 4 basic mechanisms of evolution - mutation, genetic drift, natural selection, and gene flow (migration). Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms. One of the examples of genetic drift is the bottleneck event. </span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. This is what happened to the population of worms after tree falling.
