Answer:

The theory of evolution first formulated in Darwin's book is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits that allow them to better adapt to its environment, survive and have more offspring.

Ernst Mayr divided Darwin's theory into 5 unique parts.

Ernst Mayr divided Darwin's theory into 5 unique parts.Evolution as such

Along with Buffon and Lamarck, Darwin supported the ability of species to change over time.

Common Descent

Darwin felt that all of the diversity of life on earth emerged out of the evolution from one or a few common ancestors.

Gradualism

While Lamarck felt that species-wide change could take place within the span of a few generations, Darwin felt evolution was a much slower process, taking place in innumerable small steps.

Population Speciation

This portion of Darwin's theory states that within a population, change in a species occurs as the balance of hereditary characteristics shifts across that population. This differs from Lamarck's idea that each individual in the population must undergo the same change. According to Lamarck, all giraffes living under tall trees would develop long necks. According to Darwin, some would randomly be born with long necks, this hereditary trait would gradually spread throughout the population.

Natural selection

Natural selection is often called the most unique part of Darwin's theory. Competition had been thought of as a reason that a given species might succeed or go extinct, but Darwin extended the understanding to change within a species. To continue the example of giraffes: when a giraffe is born with a longer neck than its fellows, it gains an advantage because it is able to reach more food. The long-neck giraffe is therefore stronger, lives longer, and more likely to have offspring. These offspring are born with the same long neck as their parent, though some might have even longer necks.

Returning to the example in the figure, in the first generation the application of the pesticide causes the death of most of the non-resistant insects: only those resistant to the pesticide survive. These insects reproduce and maintain their resistence so that the second generation will be more resistant than the first. So we have Natural selection, speciation, gradualism and evolution in act all together.

What is the polaris rule and how does it help you find places on earth?
juin [17]

Answer:Polaris is directly overhead (i.e. at zenith) at the North Pole and at the horizon for an observer at the equator. The rule of thumb for the altitude of Polaris is that the altitude of Polaris equals your latitude on Earth.

Although flowers have a common ancestor, they vary quite differently due to the environment and their specific pollinators. This
Ede4ka [16]

Answer:

Divergent evolution.

Explanation:

Divergent evolution can be defined as the process in which more than one group of the same species (from the same ancestors) evolve and possesses (accumulates) various features or traits such as behavior or bodily structures, thus, resulting in the formation of new species of the living organisms.

Although flowers have a common ancestor, they vary quite differently due to the environment and their specific pollinators. This is an example of divergent evolution.

Increased global temperatures have decreased disease incidence of the cattle, leading to their increased growth.

The correct option is A.

<h3>What is an example of growth?</h3>

A gradual increase in time, size, mass, or height is referred to as growth. An example of maturity is a rowdy teen who grew noticeably quieter in her late 20s. A boy that grows an inch taller between both the ages of 14 and 15 is an illustration of growth.

<h3>What causes growth?</h3>

Hormones created by the pituitary gland in the brain regulate a person's body's growth from the moment they are born. Growth hormone, sometimes referred to as human growth hormone, HGH, or GH, is the most crucial hormone for growth.

The complete question is -

Average cattle size over the past 100 years has increased steadily. Cows, on average, are more than 100 pounds heavier than they were a century ago. What is the most likely explanation of the increases observed in the cows?

A- Increased global temperatures have decreased disease incidence of the cattle, leading to their increased growth.

B- Increased water availability as water levels rise increased the growth and mass of the cattle.

C- Decreased competition with other mammal species in the wild has increased the aver-age growth rate of cattle.

D- Humans have bred the cattle to have improved genetics that increase growth rates and mass.
