What evolutionary innovation was of key significant in helping tetrapods?

Amniotes comprise all fully terrestrial vertebrates and include extant squamates, turtles, crocodiles, birds and mammals. The origin of amniotes, tightly linked to the amniotic egg as a key innovation, represents a major transition in the evolutionary history of tetrapods.

Which of the following could be considered the most recent common ancestor of living tetrapods group of answer choices?

Lobe – fin fish, which belongs to the sub class crossopterygii, is considered to be the most recent common ancestor of living tetrapod.

What evolved independently in mammals and birds?

Eardrum evolved independently in mammals and reptiles/birds -- ScienceDaily.

Which of the following are the most abundant and diverse of the extant vertebrates?

The bony fish (A) is the most abundant and diverse of the extant vertebrates. The members of the bony fish, actinopterygians, dominate the vertebrates and the fishes species in total. Actinopterygii is also known as ray finned fish.

Which major lineages make up the living Amniota?

Current research distinguishes two major lineages among amniotes: Synapsida (mammals and their extinct close relatives) and Reptilia. The most diverse group of reptiles is Diapsida (turtles, lizards, snakes, tuatara, crocodylians, birds, and many extinct groups).

What did tetrapods evolve?

Tetrapods evolved from a finned organism that lived in the water. However, this ancestor was not like most of the fish we are familiar with today. Most animals we call fishes today are ray-finned fishes, the group nearest the root of this evogram.

What were the first tetrapods to move to land?

The oldest near-complete tetrapod fossils, Acanthostega and Ichthyostega, date from the second half of the Fammennian. Although both were essentially four-footed fish, Ichthyostega is the earliest known tetrapod that may have had the ability to pull itself onto land and drag itself forward with its forelimbs.

Which was most likely food source for the first terrestrial tetrapods?

Here, the fish–tetrapod transition is represented by the osteolepiform fish Eusthenopteron (3) and the Devonian tetrapod Acanthostega, the best-known early tetrapod (14).

Are tetrapods more evolved than non tetrapods?

Tetrapods form a clade. ... Tetrapods are more evolved than non-tetrapods. Tetrapods are more closely related to each other than to non-tetrapods.

When did tetrapods evolve?

The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes.

Did tetrapods give rise to chordates?

A line of tetrapods gave rise to chordates, and a line of lobe-finned fishes gave rise to tetrapods. Tetrapods and amphibians evolved at approximately the same time, while lobe-finned fishes evolved 2 million years later.

What is convergent evolution in birds?

Convergent evolution: Convergent evolution occurs when two organisms that lack a recent common ancestor end up more and more alike as they adapt to a similar ecological niche. The organisms have convergent phenotypes, and their similar structural forms are called analogous structures (such as bird wings and bat wings).

What is convergent evolution and divergent evolution?

Divergent evolution occurs when two separate species evolve differently from a common ancestor. ... Convergent evolution occurs when species have different ancestral origins but have developed similar features. A good example of convergent evolution is the similarities between the hummingbird and the hummingbird moth.

What are tetrapods most closely related to?

The relationship of the three living groups of sarcopterygians or lobe-finned fish (tetrapods, lungfish and coelacanths) has been a matter of debate. Although opinions still differ, most recent phylogenies suggest that tetrapods are more closely related to lungfish than to coelacanths.
