Farmer joe only breeds the largest hogs, the fastest horses, or the cows that give the most milk. this is an example of artificial selection.
The process by which humans select individual organisms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve. All of our domesticated species, including crop plants, livestock, and pets, are the result of selective breeding for desirable traits such as hardy seeds and fruits, increased meat and milk production, and docile behavior.
Although the earliest artificial selection was unintentional, it evolved into a sophisticated science of plant and animal breeding; indeed, much of the field of quantitative genetics was developed to improve breeding programs.

Answer:
The scientific revolution, which emphasized systematic experimentation as the most valid research method, resulted in developments in mathematics, physics, astronomy, biology, and chemistry. These developments transformed the views of society about nature.
The answer to the statement is False.
NOTES: Global mean surface temperature from 1880 to 2018, relative to the 1951–1980 mean. The black line is the global annual mean, and the red line is the five-year local regression line.
The report of the Intergovernmental Panel on Climate Change of October 2018 showed that the difference in impact between 1.5°C and 2°C was very large. That 0.5°C increase would imply that, for example, the length of droughts would double, the occurrence of extreme weather events would more than double, and all the coral would be gone. That is why the UNFCCC Paris Agreement (COP21) of December 2015 – to which more than 190 countries have subscribed – wisely set the target of holding temperature increases to “well below 2°C” with efforts to hold to 1.5°C.
To have a reasonable chance of holding below 2°C, we have to cut emissions by around 40% absolutely in the next two decades. Much bigger cuts are necessary for 1.5°C.
<em>BONUS: </em><em>Global warming is the process of raising the average temperature of the earth's atmosphere, oceans, and land. The global average temperature on the earth’s surface has risen 0.74 ± 0.18 ° C over the last hundred years. The Intergovernmental Panel on Climate Change (IPCC) concluded that "much of the increase in global average temperature since the mid-20th century is most likely caused by increasing concentrations of greenhouse gases due to human activity" [1] through the greenhouse effect. These basic conclusions have been expressed by at least 30 scientific and academic bodies, including all national academies of science from the G8 countries.. The climate model used as a reference by the IPCC project shows that global surface temperatures will rise by 1.1 to 6.4 ° C between 1990 and 2100. </em>

Physical environment will determine the limited amount of resources that we could obtain to sustain our life.
During the process of obtaining this resource, humans are forced to connect/interact with one another.
This could happen in the form of competition where we prevent one another to obtain it , or in the form of cooperation where we work alongside each other to share the resource.
