What is common descent with modification?
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.
How does Darwin's principle of descent with modification explain the characteritics of todays species?
Yes, but it needs some additions like Mendelian Genetics that Darwin did not have. These additions have already been made.
What does descent modification imply about the relationships among the different species on earth today?
That the offspring of one species may adapt to it's surroundings and live longer then though without the modification.
Why are the Hawaiian creepers a good example of descent with modification?
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.
Why were the Galapagos islands so important to Darwin's observations?
During Darwins visit to the Galapagos island he observed that these islands had many unique organisms, most of which were similar to but different from the plants and animals from the nearest mainland.... thus this indicated how population evolved. Darwin called this "descent with modification" meaning an ancestral species could diversify into many descendant species by the accumulation of adaptation to various environment. His observation described the theory of evolution.
New generations are better suited to the environment than the first generation what is this called?
Descent with modification (Apex)
The principle that states that living species are descended from ancient ones and it is descent with?
Modification:p hope this helped
When microevolution occurs over many generations as inherited characteristics to changes in populations what has occurred?
descent with modification
When microevolution occurs over many generations as inherited characteristics lead changes in populations what has occurred?
Descent with modification
What is true Individuals are constantly evolving. Populations are constantly evolving. Evolution involves descent with modification. Acquired characteristics lead to evolution.?
Individuals are constantly evolving - False. Populations are constantly evolving - True. Evolution involves descent with modification - True. Acquired characteristics lead to evolution - False.
What is the definition of Darwin's principal descent with modification?
Darwin's principle of descent with modification suggests that all species share a common ancestor and have diversified over time through the processes of natural selection, mutation, and genetic drift. This principle forms the foundation of evolutionary theory, explaining the diversity of life on Earth.
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
What is common descent with modification?
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.

Involves descent with modification?
evolution
How does Darwin's principle of descent with modification explain the characteristics of today?
The characteristics today are what gave the best chances of survival over the last few years, decades, centuries. They were modified to best suit the circumstances surrounding their development, and the best modifications were passed on to descendants.
What is it called when newer generations are better suited to an environment than the first generation is?
descent with modification
Is descent with modification caused by natural selection?
No, it's the other way around: descent with modification is what you need for natural selection to happen.
