What scientist had ideas about evolution and adaptation that influenced Darwin?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.
What did Lamarck have to do with evolution?
Lamarck believed that there was a form of evolution, but contrary to Darwin after him, he believed that the characteristics an organism acquires during his life are inherited by its descendants. For more on Lamarck's hypothesis, see the related question below.
How can you use the concept of genetic inheritance to disprove Lamark's idea of the inheritance of acquired characteristics?
Lamarck's theory is disproved through many different examples of acquired characteristics. Anything that happens to a parent would be passed on to the offspring. Acoording to Lamarck, a parent that has tattoos would pass on the tattoos to the offspring. Loss of limb, injuries, cosmetic surgery or anything that changed in the parents would manifest in the offspring. This is not the case. Acquired characteristics are not passed on to offspring unless they change the gene sequence of the sex cells. Parents do not give physical characteristics to offspring, but do give the coding for those characteristics. The gene passes on the trait.
Lamarack's ideas about evolution include the concept that differences among the traits of organisms arise as a result of?
Lamarck's ideas about evolution include the concept that differences among the traits of organisms arise as a result of the use or disuse of those traits. This concept is known as the inheritance of acquired characteristics or the theory of soft inheritance. According to Lamarck, organisms can pass on traits that they acquire during their lifetime to their offspring.
What was incorrect about Jean-Baptiste Lamarck's theory of how organsims evolve?
One major flaw in Lamarck's theory was the idea of inheritance of acquired characteristics, which proposed that an organism could pass on traits acquired during its lifetime to its offspring. This concept has been disproven by genetics, as changes to an organism's phenotype during its lifetime cannot be passed on to future generations through its genes. Additionally, Lamarck's theory did not account for the role of natural selection in driving evolutionary change.
What is the inheritance of acquired characteristics What scientist developed this mistaken idea?
The inheritance of acquired characteristics is a discredited evolutionary theory that suggests traits acquired or modified during an organism's lifetime can be passed down to its offspring. This idea was famously proposed by French naturalist Jean-Baptiste Lamarck in the early 19th century. For example, Lamarck believed that giraffes developed longer necks because their ancestors stretched to reach higher leaves. This concept has been replaced by the understanding of genetic inheritance through natural selection, as proposed by Charles Darwin.
Which is not one of Darwin four main ideas of natural selection?
One idea that is not one of Darwin's four main concepts of natural selection is the concept of "inheritance of acquired characteristics," which was proposed by Lamarck. Darwin's four main ideas include variation within populations, competition for resources, survival of the fittest, and the inheritance of favorable traits. Unlike Lamarck's theory, Darwin emphasized that traits are passed down through genetic inheritance rather than acquired through an individual's lifetime.

Did Darwin or Lamarck hypothesized that characteristics developed by parents are passed on to their offspring?
?Mendel, widely acknowledged as the first geneticist.the answer is either lamarck or darwinit's lamarck. he believed that characteristics developed by parents are passed on to their offspring.
Is inheritance of acquired traits included in the modern theory of evolution?
No, the inheritance of acquired traits is not included in the modern theory of evolution, which is primarily based on natural selection and genetic variation. This concept, originally proposed by Lamarck, suggests that traits acquired during an organism's lifetime can be passed on to the next generation. However, modern evolutionary biology, grounded in genetics, emphasizes that only heritable traits encoded in DNA can be passed on, and acquired traits do not alter the genetic material.

What concept is selectively breeding plants and animals to accentuate certain characteristics?
artificial selection
What was lamarck's incorrect hypothesis regarding inheritance?
Lamarck's incorrect hypothesis regarding inheritance.... Lamarck did not know how traits were inherited (Traits are passed through genes) Genes are not changed by activities in life. They change through mutation occurs before an organism is born.
What concept is not a part of the theory of evolution?
Natural selection is part of the theory of evolution. The answer is transmission of acquired characteristics. Characteristics acquired but which are not genetic are not transmitted. For example, just because a person is a muscle builder, that doesn't mean his children will be really strong. Hope I helped!!
