Scientific research may explain why and how living species arise, change, thrive, perish.Boyd, Robert S
(b) Does the mutation need to be located in the coding sequence to generate a new function? If mutations are essentially a random event, explain how mutations can produce directional change in a species. (a) What is genetic drift? (b) ...
The theory was successful not only because it explained how species arise, but also because it generated new predictions that we could then test. For example, the theory of evolution explains why species appear related to one another. The Beauty in Black Holes Getty Images The connection ...
Why don't more species reproduce both sexually and asexually? What are four patterns of natural selection? Describe how fitness is achieved through various reproductive strategies centered on egg production and life history. Name and explain three ways in which genetic diversity can aris...
The relationship between plant productivity and species richness is one of the most debated and important issues in ecology. Ecologists have found numerous forms of this relationship and its underlying processes. However, theories and proposed drivers ha
Explain how spruce trees affect a key abiotic limiting factor for plant species attempting to survive on the forest floor. Using scientific reasoning, why are parts of a plant, such as the leaves, green, but other parts, such as the roots, are not?
Bacterial species often comprise well-separated lineages, likely emerged and maintained by genetic isolation and/or ecological divergence. How these two evolutionary actors interact in the shaping of bacterial population structure is currently not fully
Herbivory and disturbance are major drivers of biological invasions, but it is unclear how they interact to determine exotic vs. native seedling recruitment and what consequences arise for biodiversity and ecosystem functioning. Previous studies neglecte
Explain how the process of natural selection drives the evolution of traits within a species. What are some examples of genetic drift? How can you prevent or slow down the spread and further the selection of new antibiotic resistant strains of bacteria? Are there thi...
