LamarckismLamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also called the inheritance of acquired characteristics or more recently soft inheritance.
Charles DarwinCharles Robert Darwin ( DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental scientific concept.
The Variation of Animals and Plants Under DomesticationThe Variation of Animals and Plants Under Domestication is a book by Charles Darwin that was first published in January 1868. A large proportion of the book contains detailed information on the domestication of animals and plants, but it also contains in Chapter XXVII a description of Darwin's theory of heredity which he called pangenesis.
Cell theoryIn biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit of reproduction.
HeredityHeredity, also called inheritance or biological inheritance, is the passing on of genetic information from parents to their offspring. It may occur through sexual or asexual reproduction, where new cells are produced from either individual cells underdoing cell division or two cells combining genomes, respectively. Through heredity, genetic variations in populations can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics.
HippocratesHippocrates of Kos (; Ancient Greek: Ἱπποκράτης ὁ Κῷος, romanized: Hippokrátēs ho Kôios; c. 460 – c. 370 BC), also known as Hippocrates II, named after his grandfather Hippocrates I (also Hippocrates of Kos or Hippocrates I of Kos) was a Greek physician and philosopher of the classical period who is considered one of the most outstanding figures in the history of medicine.
Gregor MendelGregor Johann Mendel (; German: [ˈmɛndl̩]; Czech: Řehoř Jan Mendel; 20 July 1822 – 6 January 1884) was an Austrian biologist, meteorologist, mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia. Mendel was born in a German-speaking family in the Silesian part of the Austrian Empire (today's Czech Republic) and gained posthumous recognition as the founder of the modern science of genetics.
Regeneration (biology)Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystemsresilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete after which the necrotic tissue becomes fibrotic.
BiologistA biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer).
GonadA gonad, sex gland, or reproductive organ is a mixed gland and sex organ that produces the gametes (reproductive cells), and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm cells. The male gonad, the testicle, produces sperm cells, the female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells.
Greek languageIndo-European languageGreek (Modern Greek: ελληνικά, romanized: elliniká; Ancient Greek: ἑλληνική, romanized: hellēnikḗ) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family.
GameteA gamete ( GAM-eet ), reproductive cell, or sex cell, is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. The name gamete was introduced by the German cytologist Eduard Strasburger in 1878. The type of gamete an organism produces determines its sex and sets the basis for the sexual roles and sexual selection. Female gametes are called ova or egg cells, and male gametes are called sperm.*As an Amazon Associate I earn from qualifying purchases.
