What type of evolution with small scale changes in genes is called?

Some would call that microevolution. I would not. Some divide evolution into micro and macro. Evolutionary biologists prefer to use the terms evolution and speciation.

How is chemical evolution and biological evolution the same?
Chemical evolution: the evolution of the elements (building blocks of matter) biological evolution: the small scale change in a population that can be passed from generation to generation Both of these are changes that occur to gradually create a new species or substance
What is the role of genes in evolution?
Genes are the code, which when processed by a cell, result in a particular individual of a species. Slight changes (mutations) to these Genes therefore result in differences to an individual organism as compared to the rest of the members of its species. If these difference help the organism to survive and breed better than the rest of its species, then these Genes get passed on to its offspring. Thus evolutionary changes to organisms are in effect changes to the Genes which make the living organisms.
Which is macroevolution?
Macroevolution is evolution on a scale of separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes
As a group the large scale evolutionary changes that take place over long periods of time are called?
Macroevolution
Scientists have observed evolution on a rapid time scale in what organism?
Bacteria

What is the science concerned with the evolution of the cosmos?
It is called cosmology at the large scale, and nucleosynthesis at the atomic level.

What is evolution on the smallest scale?
A POPULATION
What are some types of Evolution?
Some types of evolution are;1. Macroevolution: large evolutionary change, evolution of new species from a common ancestor, evolution of one species into two or more2. Microevolution: small scale, change in gene frequencies within a population over time, changes in population accumulate, they can lead to a new species

Which temperature scale is not directly or indirectly based on a phase changes in water?
Fahrenheit Scale is the temperature scale that is not directly or indirectly based on the phase changes in water. Another similar temperature scale is Celsius Scale.
How can micro-evolution be studied?
Micro-evolution is basically evolution, ie. changes in allele frequencies, studied at the scale of a single population or species. One way to do this is to count the incidence of a particular set of traits in a population, and then to repeat the count at intervals exceeding one average life-cycle. If you're seeing a shift in the proportion of individuals carrying those traits, then you've witnessed evolution at work.
