Darwin and lamarck evolution theories
Lamarck and Darwin proposed theories to explain the evolution of giraffe necks. Lamarck's theory was that giraffe ancestors continually stretched their short necks to reach higher leaves, causing their necks to gradually grow longer over generations. Darwin's theory was that both short and long-necked giraffes originally existed together, but as trees grew taller, short-necked giraffes starved since they could not reach leaves, while long-necked giraffes survived and passed on their long necks.
darwin
Charles Darwin propuso la teoría de la evolución por selección natural, la cual explica que las especies evolucionan y se diversifican a partir de un antepasado común a través de variaciones genéticas y la selección natural de las variantes mejor adaptadas a su entorno. Darwin observó evidencia de evolución en su viaje alrededor del mundo a bordo del HMS Beagle y publicó su teoría en El origen de las especies en 1859.
Animal behaviors
Animal behavior can be innate, social, or learned. Innate behaviors are instincts, like a kitten's instinct to chase moving objects. Social behaviors include aggression over resources, territoriality to protect resources for mating and raising young, and communication through sounds, smells, and visual displays. Learned behaviors develop through experience using processes like habituation, classical conditioning, and trial and error learning.

The Gilded Age
The Gilded Age (1870-1900) was a period of rapid economic growth and industrialization following the Civil War. New factories and businesses transformed the U.S. economy and society. Wealthy industrialists and financiers accumulated vast fortunes while many workers faced difficult conditions. Political machines dominated cities and corruption was rampant. The era saw both conspicuous wealth and growing social tensions that would lead to reforms in the Progressive Era.
Charles darwin & The Galapagos Islands
Slides describes the journey of great naturalist and scientist Charles Darwin and his research at Galapagos islands.Darwin visited Galapagos islands during 18th century on his famous voyage. The main aim of the voyage was to study zoology and different animal species in each continent.
While his stay at Galapagos Darwin observed species of Giant tortoises and the Finches( also called as Darwin Finches in honor of his work). He found that there was difference in the appearance in animals of the same species relative to their habitat. This research helped Darwin to deliver the famous Theory Of Evolution. Ecuador Government established Charles Darwin Research Center at Galapagos Islands in honor of his work.
Animal Systematics Lecture 1
This document provides an overview of taxonomy and the classification of life. It discusses the early development of taxonomy from Aristotle through Linnaeus and the establishment of the binomial nomenclature system. It also describes how Darwin's theory of evolution influenced taxonomy by establishing that classification should reflect evolutionary relationships and shared ancestry. Modern taxonomy incorporates various lines of evidence including morphology, embryology, biochemistry, and molecular data to reconstruct evolutionary history and classify organisms appropriately.

Teoria da evolução das espécies 3A
Charles Darwin observou variações entre espécies nas Ilhas Galápagos e interpretou isso como resultado da adaptação aos ambientes locais. Isso o levou a propor a teoria da evolução das espécies através da seleção natural, publicando "A Origem das Espécies" em 1859.
Charles Robert Darwin[2]
Charles Robert Darwin was a famous English naturalist born in 1809 who developed the theory of evolution through natural selection. After graduating from university, he traveled on the HMS Beagle from 1831-1836, studying plants and animals. Upon his return, he published On the Origin of Species in 1859 introducing his theory of evolution. He married his cousin Emma Wedgwood in 1839 and they had ten children, though some died young. Darwin made significant contributions to scientific thought and our understanding of life on Earth.
Lamarck
Jean-Baptiste Lamarck propuso una teoría evolutiva en la que los organismos se adaptan a su entorno a través de la herencia de características adquiridas, como el cuello más largo de las jirafas. Sin embargo, la teoría de Lamarck falla porque los cambios en el uso y morfología de las partes del cuerpo no se heredan automáticamente. Darwin propuso una teoría alternativa basada en la selección natural de rasgos que mejoran la supervivencia.
Anatomia comparada aula 2
O documento discute a história e conceitos da anatomia comparada. Apresenta os principais contribuidores para o desenvolvimento da área como Linnaeus, Lamarck, Cuvier e Owen. Também aborda conceitos morfológicos como homologia, analogia e convergência, além de tópicos como simetria corporal, evolução do voo e padrões de evolução.
Evolución por Seleccion Natural
Lamarck fue la base de lo que hoy conocemos como la teoría de la evolución, Darwin y Wallace contribuyen con el concepto de Selección Natural
Elephants
The Myanmar elephant is internationally endangered and is regarded as a worldwide flagship species. Throughout their range states, the wild elephant is severely threatened by habitat destruction, poaching, and fragmentation into small isolated groups. Many population biologists believe that nowhere in Asia is there a single wild population large enough to avoid inbreeding over the long term.
1. Natural Selection
The document summarizes key aspects of Charles Darwin's theory of evolution by natural selection. It describes how Darwin observed variation among finch species on the Galapagos Islands and concluded that small populations of an original finch species from South America adapted over generations to different food sources and environments on each island, leading to the emergence of new species through natural selection. The document also contrasts Darwin's theory with Lamarck's idea of the inheritance of acquired characteristics, stating that Darwin believed advantageous traits were passed on to offspring through inheritance rather than acquisition during an organism's lifetime.

Mammalia
O documento fornece uma introdução sobre a ecologia, classificação e evolução dos mamíferos. Resume as principais características dos mamíferos, incluindo lactação, pelos, dentes e adaptações anatômicas. Também discute a classificação dos mamíferos em subclasses e ordens, com ênfase em suas origens e adaptações fisiológicas.
selective breeding and genetic engineering
Selective breeding and genetic engineering are techniques used to produce offspring with desirable traits. Selective breeding involves selecting animals with desired traits and breeding them, while genetic engineering transfers genes between organisms. Both techniques have benefits like increased crop yields or disease resistance, but also risks like loss of genetic diversity, animal health issues, or unintended effects. Genetic engineering in particular raises ethical concerns about manipulating natural organisms.
History Of American Education Part II
The document provides an overview of the history of education in the United States from the Common School Period of 1840-1880 to the present day. It discusses key figures like Horace Mann, Mary Lyon, and W.E.B. Du Bois. Major developments covered include the establishment of normal schools to train teachers, the passage of compulsory education laws, and the Morrill Act which supported the creation of land-grant colleges.
Andrology lecture 2 artificial insemination advantages and history
Artificial insemination in cattle involves collecting sperm from a male and depositing it into a female for reproduction. The document discusses the history and advantages of artificial insemination. It notes that artificial insemination was first performed in dogs in 1784 and techniques have improved over time, including the development of freezing semen in 1949 which allowed widespread use. The key advantages are using genetics from many bulls, preventing disease spread, and maintaining breeding records.
Classification (IB Biology)
The document provides information on biological classification and taxonomy. It begins with an overview of the key characteristics used to classify living things (MRS GREN: movement, respiration, sensitivity, growth, reproduction, excretion, nutrition). It then discusses the three domain system, six kingdoms, and examples of important animal and plant phyla. Specific details are provided on characteristics used to distinguish between major plant and animal phyla. The document also covers binomial nomenclature and provides examples of classification keys.
Mammals
Mammals are a class of warm-blooded vertebrates that have hair or fur and produce milk to feed their young. The document discusses the key characteristics of mammals and divides them into subclasses and orders. It provides examples and details for monotremes, marsupials, and placentals. The largest orders described are rodents, bats, cetaceans, carnivorans, artiodactyls, and primates.

Evolution
Animals change over time through the process of evolution. Some scientists believe that birds evolved from dinosaurs like Archaeopteryx due to similarities in their skeletons. There are two theories for how giraffes evolved their long necks - Lamarck's theory that giraffes stretched their necks over generations to reach higher leaves, and Darwin's theory that giraffes with longer necks were more likely to survive due to having greater access to food. Animals change through evolution in order to better adapt to their environments over many generations.

Invertebrates include sponges that live motionless at the bottom of the sea with pores, jellyfish that have poisonous tentacles, echinoderms like starfish and sea urchins that move with many small feet, worms that have a long body with rings, and molluscs that have a shell.
Chapter15 evolution(darwin)
Charles Darwin developed the theory of evolution by natural selection based on observations and evidence from his voyage on the HMS Beagle. He proposed that (1) natural variation exists between individuals of a species, (2) there is a struggle for existence as members of a species compete for limited resources, and (3) the individuals best suited for their environment (the fittest) will survive and pass on their traits, leading to the evolution of species over time. Darwin provided evidence from fossils, biogeography, embryology, and homologous structures to support his theory of common descent and evolution.
Darwin evolution revised with turning point qs
The document provides an overview of evolution and key figures in the development of evolutionary theory. It discusses early ideas on life on Earth from Aristotle and Linnaeus. It then covers contributors to Darwin's thinking like Lyell, Cuvier, Malthus, Lamarck and Wallace. Key events and theories discussed include catastrophism, gradualism, Lyell's uniformitarianism, Lamarck's inheritance of acquired characteristics, and Darwin's voyage on the Beagle leading to his theory of evolution by natural selection.
Theory of Evolution
Darwin proposed the theory of evolution by natural selection, with four main ideas: 1) Common descent, that all organisms are related through descent from a shared ancestor, 2) Gradualism, that new species arise gradually through accumulation of adaptations, 3) Multiplication of species, whereby gradual changes lead to diversification, and 4) Natural selection, the mechanism by which organisms better adapted to their environment are more likely to survive and produce offspring.

Variation: Individuen innerhalb einer Art unterscheiden sich in mehreren Merkmalen. Selektion: Zufällig besser an Umweltbedingungen angepasste Individuen überleben häufiger und geben ihre Gene damit häufiger weiter. Vererbung: Variationen in den Merkmalen sind zu einem gewissen Teil vererbbar.

Dieses neue Merkmal wird dann weiter vererbt.

Ihre Gene werden daher eher weiter gegeben, deswegen werden die Giraffenhälse auf Dauer immer länger.
