It's a struggle for existence because the animals have to do many things to survive
Charles Darwin was significantly influenced by the work of Thomas Malthus, particularly Malthus's ideas on population growth and resource limitations. Malthus argued that populations tend to outgrow their resources, leading to competition and a struggle for existence. This concept helped Darwin formulate his theory of natural selection, where those offspring better adapted to their environment are more likely to survive and reproduce. Additionally, the work of naturalists like Jean-Baptiste Lamarck and George Cuvier also contributed to his understanding of variation and adaptation.
population would be limited by food supply
no idea what the anwser is
While the idea of a zombie outbreak is a popular theme in fiction, there is no scientific evidence supporting the existence of reanimated corpses. In reality, such an event is highly unlikely.
It's a struggle for existence because the animals have to do many things to survive
Thomas Malthus's idea of population growth outstripping resources and leading to competition for survival had a significant impact on Darwin's thinking. This concept provided Darwin with insight into the struggle for existence and natural selection, which became fundamental principles in his theory of evolution. Darwin incorporated Malthus's ideas into his own work to explain how species evolve and adapt to changing environments through the process of natural selection.
I'm not sure Thomas Malthus had any theory pertaining to "evolution," strictly. Malthus was rather the prophet of "overpopulation." He put forward the idea that, if human populations kept reproducing, eventually we would crowd the world and create an ecological disaster.
explain the correlation between Darwin's theory and Malthus' idea
Malthus wrote a book that explained how resources increased arithmetically while human population increased geometrically ( exponentially ). So Darwin used this idea in showing that more organisms are born than can be supported by the environment and this set up a struggle for existence in which those organisms better suited to survive and reproduce in the immediate environment would leave more descendents in the population over time.
Thomas Malthus is the person who made the prediction that the human population would grow quicker than the resources required to sustain it. Malthus was an English scholar. Which is called Malthus' Principle
population would be limited by food supply
Thomas Malthus believed that population growth would continually outpace the ability to produce enough food, leading to a constant struggle for resources and eventual societal collapse if left unchecked. He proposed that preventive measures, like moral restraint or delayed marriage, were necessary to avoid widespread suffering and famine.
Darwin applied Malthus's idea of population growth outstripping resources to the theory of evolution by natural selection by suggesting that in nature, there is a struggle for existence due to limited resources. Organisms with advantageous traits that help them survive and reproduce in this competitive environment are more likely to pass on their genes to future generations, leading to the gradual adaptation and evolution of species over time.
His treatise on human populations growth posited that populations would grow at an exponential rate while food production would grow arithmetically. Darwin used this idea in his theory of natural selection and by observing that many more organisms are born than can possible survive with the resources the environment supplies proposed that there would be a struggle for existence that would favor the better adapted variant organisms.
Darwin was inspired by Thomas Malthus's idea that populations grow faster than the resources available to support them. Darwin applied this concept to the natural world, suggesting that individuals within a species compete for limited resources, leading to a struggle for survival. This struggle, along with natural variation and heritability of traits, forms the basis for natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring.
