What word do biologists use when they mean descent with modification?
Biologists use the term "evolution" when referring to descent with modification, which encompasses the changes in inherited traits of a population over successive generations.
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
Charles Darwin's idea of how species change over time is called what?
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.
What is descent with modification and how do fossils help it?
Descent with modification is a principal that is closely linked to natural selection. It means that the descendants of a parent species will have been slightly modified, and their descendants will be slightly modified, and so on. Natural selection is the engine that drives this modification- and ensures that this change is in a direction that better suits the species to its environment. In this way, species are constantly changing, though extremely slowly. The geological record can show how a certain species has slowly changed over time. As we follow a species through hundreds of thousands of years, parts of its organization become modified as the species becomes better suited to its environment, or to other environments that allow it to extend its range. These changes in physical aspects can be seen in fossils and show, for example, how a fin for swimming evolved into a leg for walking.
What idea of Darwin's based on fossils and the modern organism he found basically says that genetic changes are inherited by later generations?
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
New generations are better suited to the environment than the first generation what is this called?
Descent with modification (Apex)
Involves descent with modification?
evolution
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.
What is the evolutuionary theory?
The theory of descent with modification.
Fossils show evidence of descent with modification?
yes they do
Descent with modification or change over time is?
evolution
What is descent modification?
IT is when gravity collides with snakes so the organisms
What three word phrase summarizes Darwin's mechanism of evolution?
Darwin used the phrase "descent with modification" (he didn't use the term "evolution")
What word do biologists use when they mean descent with modification?
Biologists use the term "evolution" when referring to descent with modification, which encompasses the changes in inherited traits of a population over successive generations.
Is this statement true or false evolution involves descent with modification?
True.
How did Darwin explain the patterns of distribution of plants and animals?
He explained them in terms of descent with modification, common descent and natural selection.
