Summary[edit]

Description
Русский: Эволюция позвоночных от кембрия до наших дней на уровне классов в виде традиционной веретенообразной диаграммы. Ширина веретена отображает очень примерное разнообразие семейств. Диаграмма основана на Benton, M. J. (1998) The quality of the fossil record of vertebrates. P. 269–303, in Donovan, S. K. and Paul, C. R. C. (eds), The adequacy of the fossil record, Fig. 2. Wiley, New York, 312 p.

Каждый силуэт представляет традиционный класс (слева направо): бесчелюстные (Agnatha), хрящевые рыбы (Chondrichthyes), костные рыбы (Osteichthyes), земноводные (Amphibia), пресмыкающиеся (Reptilia), птицы (Aves) и млекопитающие (Mammalia). Два вымерших класса — плакодермы (Placodermi) и акантоды (Acanthodii).

Бентон отметил про своё собственное дерево, что «число семейств — несовершенная мера разнообразия». В частности, рептилии, вероятно, должны были быть более разнообразными в мезозое.

This biology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Spindle diagram-ru.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This biology image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}. For more information, see {{BadJPEG}}.
