5.1 and 5.2 Evolution Vocabulary Practice

Across
survival to reproductive age of the varieties that are best adapted to existing environmental conditions. (2 words, no space)
Type of reproduction involving the union of gametes.
evolution where species from different lineages show similar characteristics because they are subject to similar selection pressures.
the diversification of several new species from a recent ancestral source, each adapted to utilize or occupy a vacant adaptive zone. (2 words, no space)
a group of organisms of one species that interbreed and live in the same place at the same time
Cell division involving the production of gametes.
the human intervention in animal or plant reproduction to ensure that certain desirable traits are represented in successive generations. (2 words, no space)
a limb with five digits, such as a human hand or foot, which is found in many amphibia, reptiles, birds, and animals, which can allow us to deduce that all species in these categories derived from one common ancestor.
a remnant, or representation, of an organism that existed in a past geological age, or of the activity of such an organism, occurring in the form of mineralized bones, shells, etc., as casts, impressions, and moulds.
trait structures which are similar because of convergent evolution
a chemical produced by microbes to kill off competing microbes.
type of evolution in which the change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species.
an increased amount of black or nearly black pigmentation (as of skin, feathers, or hair) of an organism, resulting from the presence of melanin.
Down
the intentional breeding of organisms with desirable traits in an attempt to produce offspring with similar desirable characteristics or with improved traits. (2 words, no space)
structures derived from a common ancestor or same evolutionary or developmental origin but not necessarily in function:
an environmental variable that acts to remove poorly adapted individuals. (2 words, no space)
a naturally interbreeding group of organisms with similar morphology.
The variation in phenotypic traits in which types are grouped into discrete categories with few or no intermediate phenotypes.
the range of phenotypes within a population.
a feature of an organism that favours its survival to reproductive age. Adaptations can be behavioural, physiological, or structural.
Type of variation in which phenotypic traits, such as body weight or height, in which a series of types are distributed on a continuum rather than grouped into discrete categories.
a change in DNA.
the change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species.
