Partly yes. When organisms procreate there are always mutations, (mistakes), in the copying of the DNA. When a mutation or series of mutations helps a species to live through changes in environment it would be considered more successful and would be more likely to have offspring to pass on those mutations to the next generation.
Common descent with modification is the concept that all organisms on Earth are descended from a common ancestor, and that over time, through the process of natural selection, genetic changes accumulate in populations leading to the diversity of life we see today. This idea was proposed by Charles Darwin in his theory of evolution.
Hawaiian creepers are a prime example of descent with modification due to their evolution in isolation on the Hawaiian Islands, leading to the development of unique adaptations. As they diversified from a common ancestor, different species evolved distinct traits suited to their specific ecological niches, such as variations in beak shape for foraging. This adaptive radiation illustrates how environmental factors and geographic isolation drive evolutionary changes over time, showcasing the principles of natural selection and descent with modification.
Darwin studied modern organisms to understand how they descended from common ancestors and underwent modification over time through the process of evolution. He observed variations in traits among species and how these traits adapted to different environments, which contributed to their survival and reproduction. This concept of descent with modification emphasizes that species are not static but continually evolve, reflecting changes in both genetic variation and environmental pressures. Through his observations, Darwin laid the foundation for the theory of natural selection, illustrating how species adapt and diversify over generations.
That the offspring of one species may adapt to it's surroundings and live longer then though without the modification.
Charles Darwin used the terms "natural selection" and "descent with modification" to explain how new species emerged. Natural selection refers to the process by which individuals with favorable traits are more likely to survive and reproduce, leading to the gradual evolution of species. Descent with modification denotes the idea that species evolve over time, sharing a common ancestor while developing distinct characteristics. Together, these concepts illustrate the dynamic nature of species and their adaptation to changing environments.
evolution
True.
Individuals are constantly evolving - False. Populations are constantly evolving - True. Evolution involves descent with modification - True. Acquired characteristics lead to evolution - False.
evolution
Darwin used the phrase "descent with modification" (he didn't use the term "evolution")
Biologists use the term "evolution" when referring to descent with modification, which encompasses the changes in inherited traits of a population over successive generations.
descent with modification
The descent of modification is also known as the theory of evolution by natural selection. This concept, proposed by Charles Darwin, states that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and pass on their genes to the next generation.
Descent with modification (Apex)
Charles Darwin's idea of how species change over time is called natural selection. This process involves the survival and reproduction of organisms that are best adapted to their environment, leading to gradual changes in the characteristics of a population.
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
Darwin used the phrase "descent with modification" in his book "On the Origin of Species" instead of the word "evolution." He used this phrase to describe the process by which species change over time through natural selection.
