The word "evolution" first appeared in the English language in in a nonbiological connection, and it became widely used in English for all sorts of progressions from simpler beginnings. The term Darwin most often used to refer to biological evolution was "descent with modification," which remains a good brief definition of the process today.   The evolution of flight in insects, as well as the other three groups that independently evolved flying (bats, birds, and pterosaurs), was somewhat of a conundrum for biologists around the time On the Origin of Species was published () and for Darwin himself. Criticism focussed on the question of how complex structures can arise when a simple version of that structure cannot do the job of.

The Holometabola comprises nearly 85% of insect diversity and today contains more species than there are among plants or all other animal phyla combined ().Orders include the ants, bees, and other wasps (Hymenoptera), lacewings and antlions (Neuroptera), dobsonflies and alderflies (Megaloptera), snakeflies (Raphidioptera), twisted-wing parasitoids (Strepsiptera), beetles (Coleoptera.

  In English physician William Harvey published a book in which he proposed that caterpillars and other insect larvas were free-living embryos that Author: Ferris Jabr. Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition.

In his previous book (Larvae and Evolution, ), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa.

This leads to a new, comprehensive theory on the origin. Larvae represent one of the classic problems of evolutionary biology and may explain how new body plans originate.

It has often been suggested that many entirely unique body plans first originated as retained larvae of ancestral organisms. This book covers larval evolution and the developmental and evolutionary forces which shape and constrain them.

This chapter is an epilogue and discusses the prospects of research on the origin and evolution of larval forms. At this point two types of definitions of larvae emerge: one is characterized by morphological attributes that alter during the lifetime of the animal, often dramatically, whereas the other features ecological change during the life history of the animal.

Fish Larvae. Fish eggs hatch into larvae that are different from the adult form of the species (see Figure below). A larva swims attached to a large yolk sac, which provides the larva with food. The larva eventually goes through metamorphosis and changes into the adult form.

However, it still needs to mature before it can reproduce. Salmon Larva. A larva (plural larvae / ˈ l ɑːr v iː /) is a distinct juvenile form many animals undergo before metamorphosis into s with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.

The larva's appearance is generally very different from the adult form (e.g. caterpillars and butterflies) including different unique. Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica.

Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon.5/5(4).
