Charles Darwin

Poorly adapted organisms are more vulnerable to predation. This is one of the means by which they fail to survive as well as better adapted organisms.

Regular ones... He wanted to look good so he wore the fancy crap.... He did wear clothes tho it's confirmed... Hope that helped lol

Charles Darwin's theory of evolution by natural selection, which includes the concept of "survival of the fittest," was first published in his book "On the Origin of Species" in 1859.

The Neo-Malthusian theory builds upon Malthus's ideas by incorporating current trends and factors such as population growth, resource depletion, and environmental degradation. It emphasizes the impact of overpopulation on the environment and advocates for measures like birth control and family planning to control population growth. The original Malthusian theory focused primarily on the relationship between population growth and food supply.

1. Variation: Individuals within a species exhibit variation in traits.
2. Competition: Resources are limited, leading to competition for survival.
3. Survival of the fittest: Individuals with advantageous traits are more likely to survive and reproduce.
4. Heritability: Traits that confer a survival advantage are passed on to offspring.
5. Gradual change: Over time, the population evolves as advantageous traits become more common.

Sexual selection is a subset of natural selection that is strictly " concerned " with reproductive success. You will see organisms adapted in physiology and behavior to attract mates of the other sex with these adaptions contravening survival possibilities. Take the classic peacock example. The peacock is selected by the peahen on the basis of his tail display regardless of how such a heavy and survival risking adaption leaves the peacock open to predation. Remember, fitness is reproductive fitness and if the peacock can father most of the progeny of his local population at mating time because his tail attracts more females then what matter if he dies young.

He argued that living things have been evolving on Earth for thousands of years.

To determine if evolution by natural selection is occurring in a cactus population, you would need to observe changes in the heritable traits of the cacti over time, caused by differences in survival and reproduction. This would indicate that certain traits are being favored, leading to a shift in the genetic makeup of the population.

Natural selection is the differential reproductive success of genomic variation. But for differing variants to be able to compete reproductively, such variants must exist in the first place. Reproduction causes such variants to come into existence.

Charles Darwin observed that finches on the Galápagos Islands exhibited a variety of beak shapes and sizes, which were adapted to their specific feeding habits and the types of food available on their respective islands. This variation led him to conclude that the finches had evolved from a common ancestor, adapting to different environmental conditions through natural selection. These observations were fundamental to the development of his theory of evolution by natural selection, illustrating how species can change over time in response to their environments.

British polymath philosopher, Herbert Spencer.

Through natural selection. Certain beak types are favoured for certain food - large short beaks are better suited to eating tough seeds, while long slender beaks are better off for eating insects and small seeds. Short answer -> finches adapt by expressing different allele frequencies when exposed to different environments. The differing allele frequencies translate to different beak phenotypes, which can be advantageous depending on the environmental factors, such as the food available.

Darwin's Theory of Evolution consists of three main parts: variation, inheritance, and selection. Variation refers to differences in traits among individuals, inheritance involves passing on these traits to offspring, and selection entails the process by which certain traits become more common in a population due to their advantage in survival and reproduction.

Charles Darwin has not been discredited. He was and still is regarded as perhaps the greatest scientist that has ever lived.

Technically, yes, but only because they are using virtually the same processes, the only real difference between the two, is like the difference between choosing your own mate and having someone choose your mate for you.

because he created the natural selection

Darwin wrote a book called "Descent of Man" which delved into his theories regarding the progressive development of humans as a species. Darwin was one of the first to examine and write about the then recently discovered Neanderthal fossils, which were pretty solid evidence for the existence of hominid species ancestral to us, though Neanderthal itself was more like a cousin.

Charles Darwin was not hated during his lifetime. He was loved by his family, honored and respected among his peers.

In more recent times certain religious groups have come to view Darwin's theories as detrimental to their peculiar religious beliefs, resulting in animosity against the memory of the man and his fundamental theory of biology.

One of the most important things farmers did that improved the quality of their livestock, according to Charles Darwin, was to participate in selective breeding. This brought out the best features of each type of livestock, while ridding the offspring of unwanted characteristics.

Charles Darwin was not an inventor, he was a discoverer

The theory of evolution by natural selection.

Sexual selection.

Just to name the two most important contributions of Charles Darwin.

b. rapid change was prevalent.
