Author Item Summary Meta data
I 190
1. Stase: Most species show little change in one direction or another during their presence on Earth.
2. Sudden appearance: In all areas of life, species do not occur due to incessant changes in their predecessors, but suddenly and "fully developed".
I 191
Evolution/Gould: essentially proceeds in two ways:
a)
Definition phyletic transformation: an entire population changes from one state to another. If all evolutionary changes were to occur in this way, life would not last long. (See Evolution/Gould).
b)
Definition speciation: new species branch off from existing ones. All speciation theories assume that splits occur quickly in very small populations. Most theoreticians prefer the "allopatric" speciation (which happens in a different place). (This is the orthodox view).
With the "sympatric" speciation, new forms appear within the distribution area of the previous form.
I 198
Definition preadaption: derived from the thesis that other functions would be fulfilled in the initial stages. E.g. half a jaw could support the gills. Half a wing may have been used to catch prey, or to control body temperature.
I 240
Definition Eozoon: early form of an animal.
I 256
Definition protists: single cell precursors
Definition Metazoen: multicellular offspring.
I 258
Definition homologous similarity in common precursors: two organisms may have the same feature because they got it from a common ancestor.
Definition analogous similarity: No common precursors: If two organisms have a common feature that represents the result of a separate but similar evolutionary change in independent lines of development.
I 281
Definition parallelism, Definition convergence: a separate development of similar features in the course of evolution. This occurs very often.
II 56
Definitino Diploid: Animals with paired chromosomes in both sexes.
Some animals use a different trait for sex determination: the females are diploid, but the males have instead of each female pair only one chromosome and are considered to be the first males.
Definition Haploid denotes: only one chromosome (half of the diploid number). In other words, the males develop ironically from unfertilized eggs and have no father. Fertilized eggs, on the other hand, produce diploid females.
Animals using this system are called
Definition Haplodiploid: the males develop from unfertilized eggs and have no father. Fertilized eggs, on the other hand, produce diploid females. This can be used to control the number of females.
II 57
This fascinating system can help explain the origin of social systems in ants. Or also, for example, that a male mite dies before its own birth after fertilising its sisters in the womb.
At least 10% of all known animal species are haplodiploid.
II 186
Definition homeotic mutation: Legs or parts of legs replace a variety of structures on the head mainly antennae and parts of the mouth. Not all incorrectly placed parts are homoeoses.
William Bateson (not Gregory), who later invented the word genetics, called cases only homeotically in which organs that have the same development or evolutionary origin are replaced.
II 192
Viable homoeostats that emulate the primordial forms are not really reborn ancestors. Double elements are formed, no old patterns are found.
II 193
These things make it clear how few genes are responsible for regulating the basic order in the body of a fruit fly.
II 240
Definition Zoocentric: Perspective that derives general principles from the behaviour of other animals and then completely subsumes the human being into this category, because we are undoubtedly also animals.
Definition Anthropocentric: A point of view that tries to subsume nature in us by considering our peculiarities as the goal of life from the very beginning.
The zoocentric view can be extended to the caricature, which is often referred to as "nothing but error": the human is "nothing more than an animal (reductionism).
Popular science is flooding us with the excessively broad version of zoocentrism.
II 331
Definition "Genetic drift"/Gould: The process of random increase or decrease of the gene frequency.
II 352
Definition Clade: a branch on an evolutionary tree. The cladism tries to establish the branching pattern for a number of related species.
II 353
Definition Sister group: upside-down Ypsilon: two tribes sharing a common ancestor from which no other tribe branches off. Gorillas and chimpanzees form a sister group. We can then consider the chimpanzee gorilla group as a unit and ask which primate forms the sister group with it.
II 354
Definition derived feature: Properties that only occur for members of a direct lineage. For example, all mammals have hair, which is not the case with any other vertebrate.
II 355
Hair is a derived feature for the class of mammals, because it has developed only once in the common ancestors of mammals and therefore identifies a true branch in the family tree of vertebrates. Common derived characteristics are common to two or more strains and can be used to identify sister groups.
II 356
GouldVsCladism: Most derived features are ambiguous: they either tend to be too easily delimitable, or they are adaptive enough to be developed by several strains through natural selection independently of each other.
II 360
Definition classification (cladism): designed for the purpose of reflecting relative dimensions of similarity.
Definition Phenetism: Another theory of classification, it focuses solely on the overall similarity and tries to evade the reproach of subjectivity by referring to a large number of features, all of which are expressed numerically and processed by the computer.
II 374
Definition "Telegony": features of long extinct ancestors reappear.
"Descendants from afar." Telegony refers to the idea that a producer could influence offspring that were not conceived by him.
Definition "Pangenesis" 1868, provisionally developed by Darwin: Thesis: All cells of the body produce small particles called "Gemmulae", which circulate throughout the body, accumulate in the gametes and eventually transfer the features to the offspring.
GouldVs"Pangenesis: Since the "Gemmulae" can change, acquired features can be inherited, which would be Lamarckism.
II 377
Definition orthogenesis: The assumption that a pre-drawn path is followed.
IV 103
Doctrine of uniformity: (represented by Charles Lyell and James Hutton) the uppermost layers of the earth have remained unchanged for millions of years.
IV 153
Definition Monogeny: (19th century): Thesis: common ancestry of all humans from the ancestors Adam and Eve. (Lower races were later degenerated from original perfection).
Definition Polygeny: (19th century): Thesis: Adam and Eve are only the ancestors of the white peoples.
IV 159
Definition subspecies: Population inhabiting a specific geographical area.
IV 357
Definition sympatric: at the same place
Definition allopatric: in separate places (assuming that species can only develop separately).
III 19
The "Full House": Gould's central argument: natural reality is an accumulation of individuals in populations. Variation is not reducible but "real" in the sense that "the world" consists of it.
Error: To always describe populations (according to Plato) as "average", which is then considered "typical".
III 67
The "Full House": the need to focus not only on an abstract measure of an average or a central tendency, but on the variation within whole systems.
Error: likely outcome for a single individual to be considered as a measure of a central tendency.
