Who was the first to actually attempt to explain the mechanism by which species change?
The first to attempt to explain the mechanism by which species change was Jean-Baptiste Lamarck in the early 19th century. He proposed the theory of inheritance of acquired characteristics, suggesting that organisms can pass on traits acquired during their lifetime to their offspring. However, his ideas were later challenged and largely replaced by Charles Darwin's theory of natural selection, which provided a more comprehensive explanation of evolutionary processes.

Natural selection is the mechanism which proved species?
Natural selection is the mechanism by which species evolve over time as individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Through this process, species gradually adapt to their environment, leading to changes in their characteristics and behaviors. This drives the diversity and complexity of life on Earth.
How did the identification of genes help explain evolution?
The discovery of the structure of the genome and the genetic mechanism helped explain what the mechanism was that drives evolution: it helped explain how changes in the genome lead to the different phenotypes upon which natural selection acts. Also, the ability to sequence parts of a genome yielded yet another confirmation of the central thesis of common descent, by showing that at the genetic level all life conforms to the same set of nested hierarchies that was already apparent in its morphology and behaviour. Thirdly, the ability to compare genes and genomes allowed biologists to establish much more accurately the evolutionary relationships between species.
What did Darwin's theory of evolution provide that earler theories of evolution had not?
Darwin was by no means the first person to come up with a theory of evolution. However, he was the first person provide a mechanism by which evolution could occur. He called this natural selection and is essentially the way in which individuals with characterisitcs that better suit their environment survive and ones which don't die out. Therefore, eventually the whole species will possess these advantageous characteristics and evolution will have occured.
Who proposed natural selection as a mechanism of evolution?
At the Linnaen Society meeting sometime in 1858 Charles Robert Darwin and Alfred Russel Wallace had both their papers presented before the Society on which they proposed the idea of natural selection as a mechanism of evolution.
Does Mycobacterium smegmatis have endospores?
No, Mycobacterium smegmatis does not form endospores. Endospores are typically formed by some bacterial species in response to harsh environmental conditions as a survival mechanism, but Mycobacterium species, including M. smegmatis, do not produce endospores.
What question did Charles Darwin attempt?
Charles Darwin attempted to answer the question of how species evolve and adapt to their environments, proposing the theory of natural selection as the mechanism driving this process.
What did Darwin assert in his book On The Origin of Species as the mechanism of evolution?
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
What was Darwin's major problem?
Darwin's major problem was resolving the mechanism of evolution, how new species arise from existing ones. He struggled to explain how traits could be passed on and eventually lead to the formation of new species without a clear understanding of genetics. His solution, natural selection, was groundbreaking in explaining how species evolve over time.
How did creationist attempt to explain the existence of fossils that resemble species that people had never seen before?
They say that there were more animals before that went extinct, but the animals that are here today survived and are still here.
Explain how four species of lizards all closely related came to be separate species on a Caribbean island?
explain how four species of lizards all closely related came to be separate species on a Caribbean island.
What are Darwin's finches a great example of?
Darwin's finches are a great example of adaptive radiation, where a common ancestor species diversifies into multiple species to exploit different ecological niches. This process of adaptive radiation is a key mechanism in evolutionary biology to explain the diversity of life forms.
Is natural selection a fact or theory?
Natural selection is a scientific theory proposed by Charles Darwin to explain how species evolve over time. It is based on strong evidence from observations and experiments, making it widely accepted as a fundamental mechanism of evolution.
Why did Charles Darwin started the theiry of evolution?
To explain the species problem, " that mystery of mysteries " which was the natural history problem of the day. From his observations and experiments Darwin proposed his theory of evolution by natural selection, which provided a mechanism for the observed fact of evolution.
Which mechanism do the different organism populations found across the tundra exemplify?
Species diversity :)
Where do you find the chassis number on a sandman?
You can attempt to, but seeing that the sandman is a protective endangered species with aggressive behavior, i wouldn't attempt to do so
How many species of worm exsits?
there are actually 35,000 species.
What does Charles Darwin's theory of evolution not explain?
Charles Darwin's theory of evolution does not explain the origin of life itself, but rather how different species have evolved over time through natural selection. It also does not explain the mechanism of inheritance of traits, which was later elucidated by Gregor Mendel's work on genetics. Additionally, there are still gaps in our understanding of specific evolutionary pathways and processes, especially at more detailed levels.
