Type of evolution in which unrelated organisms independently evolve similarities when adapting to similar environments?
Analogous selection.
What is the important concept in Darwin's theory of evolution by natural selection?
The theory of evolution was developed by Charles Darwin. He sailed on the HMAS Beagle to the Galapagos islands. He said that the finches were very similar, but had different beaks. This was probably so they didn't have to compete with other birds for food. They evolved by natural selection. This means that the bird with features best suited to the environment would breed and pass their characteristics on to the next generation. Birds not suited would die. This also happens with bacteria. Bacteria with a natural resistance to antibiotics would survive, breed and pass their genes onto the next generation.
How do living things and non living things effect each other?
Living conditions such as other similar organisms to an organism in question often results in competition for food, nutrients, and / or shelter. Natural selection is usually a result of this (natural selection is where the strongest survive), leading to evolution and development of the species. The environment, in turn, benefits from natural selection due to the decreased number of organisms draining resources. In essence, it is a cycle, with the living depending on the nonliving / other living, those being depended upon running short, the depending fighting each other, and the depended upon benefiting as a result.
What evolution is called when unrelated organism live in similar environment?
And come up with similar solutions, both physiological and behavioral? Analogous structures arising from convergent evolution.
What are examples of structural evidence of evolution?
Similar bone structures in species
Who proposed a theory of evolution by natural selection that was similar to Darwin's theory?
Alfred Russel Wallace. Google him.
Who inventen the theory or evolution?
Charles Robert Darwin and Alfred Russel Wallace developed similar and almost simultaneous theories of evolution by natural selection.
What was Wallace contribution to the theory of natural selection?
Wallace's contribution was almost similar to what Charles Darwin's theory of evolution is. Is that helpful?
Briefly describe two ideas about evolution that were proposed by scientist in the 18th century?
Darwin Which was the theory of evolution by natural selection. this is where the fittest species survive and pass on their traits. Lamarack which is the theory acquired characteristics . similar but wrong where it states animals will adapt and chage there thraist to fit in the environment and pass on their traits
How did Darwin explain why Galapagos species had different adaptions and similar South American species?
Define the term Variation and natural selection how do they work together to help cause evolution
What best describes how a species changes over time?
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.
How is mutation and natural selection similar?
Both establish that: 1. There are limited reproductive opportunities 2. Only those organisms with "favorable" traits will be allowed to reproduce and pass the traits onto their offspring The difference is that artificial selection involves human intervention
Type of evolution in which unrelated organisms independently evolve similarities when adapting to similar environments?
Analogous selection.
How is cultural evolution similar to natural selection?
Cultural evolution is the phenomenon whereby cultural ideas, notions, views, etc. propagate throughout populations, like alleles propagate throughout population gene pools in biological evolution.Some propose that the way these ideas propagate throughout populations is similar to the ways of biological evolution, in that cultural ideas (or memes) are subject to a kind of cultural selection, that determines how fast they spread, and to what degree.
How is the study of evolution similar to the study of history?
One reason is that you are studying the past and evolution is a poor predictor of what will happen in the future. What is can predict is what is happening now with organisms Just like the study of history except the testable hypotheses that can be generated from the theory of evolution by natural selection are much more precise than historical analysis.
Were Darwin's hypothesis about natural selection and evoultion similar to the other scientist of his time?
Only one other scientist at the time had the theory of evolution worked out and his name was Alfred Russell Wallace who wrote a book at the same time.
What are some similarities in divergent and convergent evolution?
The adaptive traits that arise through convergent evolution are called analogous. These are the same adaptive solutions that arise in different organisms facing very similar environmental challenges and having analogous mutations to come to similar traits through natural selection. Wings in birds, bats and insects are examples of this.
