What key component is missing in Darwin's theory?
Darwin, when he first wrote of the origin of species and Natural Selection could not have known of genetics. Mendel began his experiments around the time of the great beginning of Nature-selection Darwinism, but its publication was not synchronous with the first of Darwin's ideas.Darwin propounded that traits/characters were selected naturally as to how good they were at fitting in with the environment. This is a profound argument and Darwin probably only based it on morphological characters, such as the neck-shapes of tortoises, the flightlessness of Galapagos cormorants and the bill-masses of what are now called Darwin's finches. He could see how morphology matched and changed with environment but could not have known, due to the distance of Mendel, what substance, what mechanism brought about these characters and changes; this 'descent with modification'.What was missing was genetics. These days, Darwin's theory has been elaborated into the Modern Synthesis, which now encompasses genetics and thus has a real substance, like an ether that permeated the pre-Eisteinian universe, to bring about all evolutionary character-change.
What is the Charles Darwin's idea of evolution?
That marshmallows are delicious and must be passed on to the next generation so that they might enjoy the deliciousness of marshmallows too. HE (as in God, as in Darwin, as in my GReat-gGreat-Great Grandmother) believed in passing on the good memories.
Why is it important for organisms of the same species to have a diversity of genes?
To frustrate parasites. A monoclonal culture is open to devastation to the first good pathogen.
What is a good example for unicellular organism and multicellular organism?
You are a good example of a multicellular organism and Escherichia coli, the microorganism living symbiotically in your intestine, is a good example of a unicellular organism.
Why some Scientists disagree with Charles Darwin's work?
Due to : 1- Religious beliefs 2- there were different theories 3- there was no good explanation
The varieties of beak sturctures among galapagos finches is a good example of?
The varieties of beak structures among Galapagos finches is a good example of adaptation. Temperature and food sourcing influence the development of the differing beaks.
Why are finches in the Gal and aacutepagos Islands a good example of speciation?
Answer this question… . Galápagos finches have different kinds of beaks that match food sources.
How did the finches help Darwin to formulate his theory of natural selection and evolution?
There were many islands and finches on each. The finches did not fly from their home island to other islands. Different islands had different food for the finches. Darwin noticed that where there were plenty of honeysuckle flowers for the birds to feed on, the finches there had long beaks. On islands where the best bird-food was small seeds, the finches had beaks more like canary beaks, short and strong. Darwin also noticed that the finches were all from the same original flock and had probably mixed up when the islands were closer together and they could fly to any island to feed. So Darwin concluded that when the finches became isolated on different islands, their beaks evolved to be most suitable for eating the food available. The birds with the wrong beaks died young and had few chicks and these chicks unfortunately for them inherited their parents silly beaks. The birds with the right beaks fed well and had lots of chicks who inherited good beaks. So eventually nearly all the finches on any given island had the most suitably shaped beaks.
How are finches in the Galápagos a good example of adaptation?
they have adapted to be able to get different types of food. -apex
How did Charles Darwin solve the theory of evolution?
Evolution was seen by many. But the mechanics were not well understood. One of Darwin's observations involved finches in the different Galapagos Islands. Each island had finches with slightly different physical attributes. Charles Darwin noticed that the shape of their beaks were different, depending on their primary food. Some beaks were shaped to make eating seeds more efficient. Others were shaped to eat insects. The finches that Darwin brought back as stuffed specimens, are still present in the British Museum. The collection is mounted, and it is easy to see the differences. Darwin felt that all of these different finches were descendants of finches that were blown on to the islands during a storm. Darwin was able to show that small differences gave finches on various islands an advantage. After many generations, each island had finches whose differences were very obvious. According to Darwin, the finch that lived on a specific island, did not choose to change. But small changes in beak structure, gave those birds an advantage. They were able to gather more food, and eventually had more living offspring. A good example are dandelions growing on a lawn. The lawn mower is set at a specific height. As you mow your lawn, the taller dandelions have their tops cut off. No flowers, they can't reproduce. But the few shorter dandelions are left, their pollen reproduce, and now most of the dandelions are short, close to the ground, and difficult for the lawn mower to cut them off.

How are finches in the Galapagos is lands a good example of adaptation?
These birds, although nearly identical in all other ways to mainland finches, had different beaks. Their beaks had adapted to the type of food they ate in order to fill different niches on the Galapagos Islands. Their isolation on the islands over long periods of time made them undergo speciation (form new species).Darwin wrote about his travels in the book The Voyage of the Beagle and fully explored the information he gained from the Galapagos Finches in his most famous book On the Origin of Species.It was in that publication that he first discussed how species changed over time.
What are the disadvantage of eugenics?
Lack of diversity (inbreeding) exposing genetic weaknesses. A good example would be pedigree dogs.
How are finches in the Galapaagos Islands a good example of adaptation?
Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
