24.4 Evo-Devo: Evolutionary Developmental Biology

Sponges

________ have bodies that are not organized along a body axis.

Polyploidy

________ may produce individuals with novel shapes and forms.

second duplication

The ________ may have been a critical event that led to the evolution of multi- limbed animals.

Research

________ shows that one directs the formation of certain regions of the body.

genetic changes

A rapid rate of evolution could occur via allopatric or to reproductive isolating mechanisms that prevent closely related speciation, in which a small group migrates away from a larger species from interbreeding. These ________ result in morpho population to a new environment in which different alleles provide logical and physiological differences that distinguish one species from better adaptation to the surroundings.

Fruit flies

________ have one segment in the middle of the body that is more complex.

Genetics

What were considered in the development of plants and animals? Answer with a single words or term.

Anemones

________ have a primitive body axis.

Habitat isolation

What is one of the characteristics of prezygotic isolating mechanisms? Answer with a single words or term.

Gremlin

What is not expressed in the interdigit regions of the chicken but in the regions of the duck? Answer with a single words or term.

Flatworms

What are more complex than insects, but less complex than organisms with a spine? Answer with a single words or term.

Bilaterians

What are organisms? Answer with a single words or term.

small genetic changes

What were consistent with gradualism? Answer with a single words or term.

primitive 2

The ________- celled eye can be interbred if two populations are separated.

Natural selection

________ may lead to a better understanding of bio a rapid evolution of the gene pool by favoring those alleles that logical development at the molecular level.
