What is the difference between analogous and homologous?
Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.

Do dogs have pentadactyl?
Yes they do
Do dogs have pentadactyl limbs?
yes they do
Do humans have pentadactyl limbs?
yes
Do bats have pentadactyl limbs?
Bats do have pentadactyl limbs. Its wing is the forelimb version of the pentadactyl limb. In the bat, the forelimbs have turned into wings for flying by great elongation of four digits, while the hook-like first digit remains free for hanging from trees.
What is the root word pentadactyl?
The root word in pentadactyl is "penta," which means five. In biology, "pentadactyl" refers to having five digits, such as fingers or toes.
Do bats have two arms and two legs?
Yes, bats do have four limbs,pentadactyl limbs.
How is homo-logy in the pentadactyl limb evidence for adaptive radiation?
Homology in the pentadactyl limb, where different species share a common limb structure despite having different functions, is evidence for adaptive radiation because it suggests that a common ancestor with this limb structure diversified into various species to adapt to different environments or ecological niches. The conservation of the pentadactyl limb's basic structure implies that these species diverged from a shared ancestor through adaptive changes to exploit different habitats and resources.
What is the root meaning of pentadactyl?
Having five digits to the hand or foot., Having five appendages resembling fingers or toes.
What is a pentadactyl appendage?
I will focus on the on the pentadactyl FORELIMB (arm). It is the limb that is common in vertebrates (e.g. humans, birds, dogs, whales, bats ALL HAVE ONE!). It supports the theory of evolution by strengthening the idea of divergent evolution and the idea of a common ancestor by showing that different environmental conditions and different selective pressures can result in vastly different characteristics being selected in common species. Each limb consists of: * humerus - upper arm * radius - forearm * ulna - forearm * carpals - wrist * metacarpals - palm * phalanges - fingers/digits Due to the fact that various organisms have a pentadactyl limb, it is difficult to give a definite answer to what it looks like because it varies from organism to organism. Think of as your own arm as an example of a pentadactyl limb to get a clearer image in your head: * from your shoulder to your elbow is the humerus * from the elbow to the wrist are the ulna and radius * your wrist is the carpal * your palm is the metacarpal * your fingers are the phalanges
What is the root word of pentadactyl?
Dactyl is actually a word fragment from the Old Greek 'dactylos' - two-jointed (three segment) finger, first (English) attested 1498, its origin predates written Greek by (at least) centuries
When were horses in the us?
Over 55 million years ago horses first evolved. They were only the size of an average dog and they had a pentadactyl limb (finger like structures instead of one hoof as we know today.) This enabled them to walk around as the Earths surface was covered in marshland and they needed the splayed out feet in order to do this, otherwise they would sink and would be unable to run from predators.
How is anatomy used as evidence for evolution?
Anatomy is a useful tool in gaining evidence for evolution. The most useful thing is to examine homologous structures, ie anatomical similarities between different species. The best example of this is the pentadactyl limb. It is found in humans, dolphins and bats. This shows that at some point in the past there must have been a common ancestor from which these 3 diverse groups of animals evolved.
